Loop ligature device for bladder tumor

Abstract

The invention discloses a loop ligature device for a bladder tumor, which comprises a loop ligature device body and a loop ligature metal coil, wherein the loop ligature device body takes the shape of a hollow cavity, one end of the loop ligature device body is connected with a handle, on end of the handle is connected with a binding post, the binding post is located in the hollow cavity in the loop ligature device body, a flexible insulation sleeve is connected onto the binding post, the loop ligature metal coil is led in from an on-point of the binding post and led out from an off-point of the binding post and is simultaneously sleeved in the flexible insulation sleeve and a lower flexible insulation sleeve, the on-point and the off-point of the binding post are respectively connected with electrodes, and the electrodes are connected with an external power source. The loop ligature device for the bladder tumor is simple in structure and convenient in operation, the field is clear in the operation process, and the directivity and the controllability of the operation can help to completely remove the tumor better and shorten the operation time.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a ligature for bladder tumors. Background technique [0002] Transurethral resection of bladder tumor is the most commonly used treatment method for the removal of superficial bladder tumors. It has the advantages of small damage, quick recovery, and repeatability. It has become the gold standard for the treatment of non-muscular invasive bladder cancer. However, traditional resectoscopes have the following shortcomings in the removal of bladder tumors, especially large pedicled tumors with a tumor diameter greater than 3cm: 1. The tumor is soft, drifting, and not fixed, and it lacks good tactile feedback and is time-consuming 2. The blood supply of the bladder tumor is at the root. Removal of the tumor surface before the root is removed can easily lead to bleeding and unclear vision, which may cause bladder perforation; 3. Cutting the tumor in pieces increases the potential risk of t...

AI Technical Summary

Problems solved by technology

However, the traditional resectoscope has the following disadvantages when resecting bladder tumors, especially large pedunculated tumors with a tumor diameter greater than 3 cm: 1. The tumor end is soft, drifting, and not fixed, and it lacks good tactile feedback during resection and is time-consuming ; 2. The blood supply of bladder tumors is at the root. Excision of the tumor surface before the root is easy to cause bleeding and blurred vision, which may cause bladder perforation; 3. Cutting the tumor in pieces increases the potential risk of tumor cell shedding and planting ;4. Some special tumors, such as tumors on the anterior wall, require assistants to continuously press the suprapubic area to expose the tumor, and the air bubbles generated during the electric resection can easily interfere with the operation, which puts forward higher requirements for the experience and skills of the operator
