Abstract
Various stabilizers for supporting a trocar and stylet are disclosed. In some implementations, a stabilizer may include a main portion through which a trocar and stylet may be inserted and supported, and a plurality of stabilizing portions to prevent movement of the stabilizer when the stabilizer is placed on a patient's body.
Claims20
A method, comprising:
- placing a stabilizer over an entry point in a patient's body;
- inserting a trocar and a stylet into the stabilizer,
- wherein the stabilizer comprises:
- a main portion through which the trocar and the stylet is inserted;
- and
- a plurality of stabilizing portions of the stabilizer,
- wherein the plurality of stabilizing portions are configured to be removable from the main portion based on at least one of perforated sections or lines between the main portion and the plurality of stabilizing portions, and
- wherein the at least one of the perforated sections or the lines are configured to enable adjustment of a size of the plurality of stabilizing portions by removing a subset of the plurality of stabilizing portions;
- generating a radiological image to determine if the trocar and the stylet are inserted at a correct trajectory;
- advancing the trocar and the stylet into the patient's body at the entry point based on determining that the trocar and the stylet are inserted at the correct trajectory;
- removing the stylet from the trocar based on advancing the trocar and the stylet into the patient's body;
- inserting a biopsy tool into the trocar;
- performing a biopsy using the biopsy tool;
- removing the biopsy tool from the trocar and reinserting the stylet into the trocar;
- and
- removing the trocar and the stylet from the patient's body through the stabilizer.

A system, comprising:
- a trocar;
- a stylet;
- and
- a stabilizer,
- wherein the stabilizer is placed over an entry point in a patient's body;
- wherein the trocar and the stylet are inserted into the stabilizer,
- wherein the stabilizer comprises:
- a main portion through which the trocar and the stylet is inserted, and
- a plurality of stabilizing portions of the stabilizer,
- wherein the plurality of stabilizing portions are configured to be removable from the main portion based on at least one of perforated sections or lines between the main portion and the plurality of stabilizing portions, and
- wherein the at least one of the perforated sections or the lines are configured to enable adjustment of a size of the plurality of stabilizing portions by removing a subset of the plurality of stabilizing portions,
- wherein the system is configured to be used with a biopsy procedure, wherein the biopsy procedure comprises a radiological image that is generated to determine if the trocar and the stylet are inserted at a correct trajectory,
- wherein the trocar and the stylet are advanced into the patient's body at the entry point based on determining that the trocar and the stylet are inserted at the correct trajectory,
- wherein the stylet is removed from the trocar based on advancing the trocar and the stylet into the patient's body,
- wherein a biopsy tool is inserted into the trocar,
- wherein a biopsy is performed using the biopsy tool,
- wherein the biopsy tool is removed from the trocar and reinserting the stylet into the trocar;
- and
- wherein the trocar and the stylet are removed from the patient's body through the stabilizer.
16 more elements
A device, comprising:
- a stabilizer,
- wherein the stabilizer is placed over an entry point in a patient's body;
- wherein a trocar and a stylet are inserted into the stabilizer,
- wherein the stabilizer comprises:
- a main portion through which the trocar and the stylet is inserted, and
- a plurality of stabilizing portions of the stabilizer,
- wherein the plurality of stabilizing portions are configured to be removable from the main portion based on at least one of perforated sections or lines between the main portion and the plurality of stabilizing portions, and
- wherein the at least one of the perforated sections or the lines are configured to enable adjustment of a size of the plurality of stabilizing portions by removing a subset of the plurality of stabilizing portions,
- wherein the device is configured to be used with a biopsy procedure, wherein the biopsy procedure comprises a radiological image that is generated to determine if the trocar and the stylet are inserted at a correct trajectory,
- wherein the trocar and the stylet are advanced into the patient's body at the entry point based on determining that the trocar and the stylet are inserted at the correct trajectory,
- wherein the stylet is removed from the trocar based on advancing the trocar and the stylet into the patient's body,
- wherein a biopsy tool is inserted into the trocar,
- wherein a biopsy is performed using the biopsy tool,
- wherein the biopsy tool is removed from the trocar and reinserting the stylet into the trocar;
- and
- wherein the trocar and the stylet are removed from the patient's body through the stabilizer.
