Description

Bladder tumor sleeve basket

Technical Field

The utility model relates to the field of medical equipment, concretely relates to bladder tumour cover basket.

Background

Bladder cancer is a common malignancy. The incidence rate of bladder cancer in the national tumor registration area in 2009 is 6.61/10 ten thousand, and the standardized rate of Chinese population is 3.03/10 ten thousand. In patients with bladder cancer, non-muscle invasive bladder cancer accounts for 70% of the initial bladder cancer. Transurethral cystotomy (TURBT) is an important diagnostic and primary treatment for non-muscle invasive bladder cancer. When the tumor is located on the lateral or posterior wall, the electrocision procedure may cause obturator nerve reflex, resulting in complications such as bladder perforation.

The laser does not cause obturator nerve reflex, and with the gradual popularization of laser in various hospitals, transurethral bladder tumor laser enucleation also gradually replaces TURBT. The transurethral laser surgery can accurately and completely enucleate tumors, and has obvious advantages compared with TURBT. However, for tumors larger than 0.5cm, tumor retrieval becomes a troublesome problem after complete enucleation of the tumor. If the tumor is directly taken out by foreign body forceps under the cystoscope, the tumor can contact urethral mucosa, so that the risk of tumor urethral planting is increased; the tumor is taken out after being cut into blocks, so that the operation time is increased, and the possibility of scattering of the tumor is increased.

There is therefore a need for a device that can grab a tumor after it has been completely resected, and be directly removed transurethrally, while avoiding direct contact of the tumor with the urethral mucosa.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a bladder tumor basket which can grasp and draw the tumor in the operation and is convenient for the operation; meanwhile, the direct contact between the tumor and urethral mucosa is avoided, and the risk of tumor urethral planting is reduced.

The utility model discloses a technical scheme that technical problem solved took is:

the bladder tumor sleeve basket comprises a sleeve, a first limiting ring, a first steel wire, a first operating rod, a second operating rod, pull rings, a traction device, a second limiting ring, three steel wires and a sleeve basket, wherein the sleeve basket is arranged inside the sleeve, the first limiting ring is three, the second limiting ring is one, the first steel wire is three, the second steel wire is one, the first steel wire and the second steel wire are all connected with the sleeve basket, the first steel wire penetrates through the first limiting ring and the first limiting ring in sliding connection respectively and is welded with the first operating rod, the second steel wire is welded with the second operating rod, the second limiting ring is welded with the second operating rod, the sleeve basket is further connected with the traction device, and the traction device penetrates through the inside of the sleeve and extends out of the end part of the sleeve and is connected with the pull rings at the tail part of the sleeve.

Further, a membrane is arranged on the basket.

Wherein the basket is pocket-shaped and has an opening which can be extended and contracted.

Preferably, the traction device is a string or a wire.

The specific working method of the bladder tumor basket comprises the following steps:

1. after the bladder tumor basket enters the bladder from the urethra, the sleeve is retracted, the sleeve extends out of the sleeve by the thrust of the first steel wire and the second steel wire, and the opening of the basket is slightly expanded by the inherent elasticity of the steel wires;

2. the first operating rod and the second operating rod are continuously opened, the second limiting ring moves backwards along with the operating rods, the first three steel wires move forwards along with the operating rods and are further separated under the action of the first limiting ring, so that the basket is opened, and meanwhile, the basket can be forwards tilted because the second steel wires move backwards along with the second operating rod, so that tumor tissues can be conveniently sleeved.

3. Pulling the traction device, sealing the sleeve basket and pulling out.

The specific advantages of the bladder tumor basket of this application:

1. to the bladder tumor with pedicle with the size within 2cm, the utility model can grip and draw the tumor in the operation, thereby facilitating the operation.

2. After the tumor is completely resected, the tumor can be grabbed and directly taken out through the urethra, meanwhile, the tumor is prevented from being directly contacted with urethral mucosa, and the risk of tumor urethral planting is reduced.
