Transurethral double-operation-channel bladder tumor laser monoblock excision equipment

Abstract

The invention discloses transurethral double-operation-channel bladder tumor laser monoblock excision equipment, which comprises an outer sheath, an operation sheath, a cystoscope endoscope, a laser optical fiber, traction pliers and pushing pliers, wherein the outer sheath comprises an outer sheath body, a water feeding connector and a water discharging connector; the inner end side wall of the outer sheath body is provided with a plurality of perfusion holes; the operation sheath comprises a bladder endoscope operation pipe, a laser operation pipe and an auxiliary pliers operation pipe, wherein the bladder endoscope operation pipe, the laser operation pipe and the auxiliary pliers operation pipe are arranged in parallel, and the operation sheath can be put in the outer sheath body; the bladder endoscope comprises an eyepiece, an endoscope body, an objective lens and a light guiding barrel, wherein the endoscope body of the bladder endoscope can be put in the bladder endoscope operation pipe; the laser optical fiber can be put in the laser operation pipe; the traction pliers and the pushing pliers independently comprise a handle, a pliers rod and a pliers head and can be put in the auxiliary pliers operation pipe; the pliers clamping surface of the pliers head of the traction pliers has a fine grained structure, and the outer end of the pliers head of the traction pliers has a mouse tooth structure; the handle has a buckling and locking structure; and the pliers clamping surface of the pliers head of the pushing pliers has a sawtooth structure. The transurethral double-operation-channel bladder tumor laser monoblock excision equipment has the advantages that a surgeon can conveniently operate the transurethral double-operation-channel bladder tumor laser monoblock excision equipment, operation is more accurate, an applicable range is wide and the like.

Description

technical field [0001] The invention belongs to the field of surgical instruments, and relates to a laser resection device for bladder tumors, in particular to a laser en bloc resection device for bladder tumors with double operation channels through the urethra. Background technique [0002] Bladder cancer is one of the most common tumors in urology clinics. Worldwide, bladder cancer ranks ninth among malignant tumors. In my country, the incidence rate of bladder cancer in the national tumor registration area in 2015 was 5.8 / 100,000, ranking 13th in the incidence rate of malignant tumors. [0003] The staging of bladder cancer refers to the depth of tumor infiltration and metastasis, and is one of the most important indicators for judging the prognosis of bladder cancer. According to the depth of tumor invasion, it can be divided into non-muscle-invasive bladder cancer (including TIS, Ta, T1) and muscle-invasive bladder cancer (above T2). In nearly 75% of bladder cancer ...

AI Technical Summary

Problems solved by technology

4. A higher proportion of specimens has detrusor tissue, which may reduce the rate of secondary resection, reduce the recurrence rate, and may improve the prognosis of patients

The bladder is a hollow organ, and the location of the tumor varies greatly. Only a single operation channel combined with direct laser has a limited scope of application. Tumors on the anterior wall and top wall of the bladder are difficult to treat, and the scope of application is limited.
