[0005] However, when using a conventional uterine fibroid pulverizer for surgery, since the length of the knife tube is greater than the length of the scabbard, the cutting edge of the knife tube will protrude from the lower port of the sheath body; Fibroid cells, cell clusters or tissue fragments leak and scatter in the abdominal cavity by breaking the crushed bag, causing contamination; there are defects such as difficult operation and high risk of contamination
In addition, the sheath of the uterine fibroid pulverizer of the traditional structure is not provided with an air inlet and an exhaust port, and the rotary cutting pulverizer must be taken out of the scabbard before it can be inflated into the pulverizing bag through the upper port of the scabbard; not only The operation is cumbersome, and it is impossible to supply or exhaust air into the crushing bag during the fibroid crushing process

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the drawings and specific embodiments:
[0015] Such as Figure 1~3 As shown: the present invention is composed of a scabbard and a rotary cutting and pulverizing knife that has a circular tubular structure and is matched with the scabbard. The scabbard is composed of a funnel-shaped sheath body 4, a screw sleeve 2 fixed to the upper port of the sheath body by threads, an upper sealing cap fixed at the top end of the screw sleeve 1, a lower wind cap fixed at the bottom end of the screw sleeve 3, Two valves 9 fixed on the sheath body 4 are formed. The lower port 5 of the sheath body 4 is an oblique cut or an inwardly curved curved cut-shaped structure; the rotary cutter includes a front nozzle with a wavy blade (Not shown in the figure) knife tube 8 and a disc-shaped knife tube seat 10 fixed on the knife tube. When the knife tube 8 passes through the upper cap 1, the screw sleeve 2, and the lower ai...

The invention provides a uterine fibroid or uterine body rotary cutting grinder and aims to provide a uterine fibroid grinder which can prevent damage of a grinding bag and is simple and convenient to operate. The uterine fibroid or uterine body rotary cutting grinder comprises a circular tube rotary cutting grinding cutter matched with a sheath; the sheath comprises a sheath body (4) in the shape of a funnel, a thread insert (2) fixed at the upper end opening of the sheath body, an upper sealing cap (1) fixed at the top end of the thread insert, and a lower air cap (3) fixed at the bottom end of the thread insert. The rotary cutting grinding cutter comprises a cutter tube (8) provided with a cutting edge at the front end tube opening, and a cutter tube base (10) fixed on the cutter tube. At least one valve (9) is fixed to the sheath body (4). The lower end opening (5) of the sheath body is n inclined groove or an inward-bending curved groove. The front end tube opening of the cutter tube (8) is located between the lowest portion and the highest portion of the lower end opening. The uterine fibroid or uterine body rotary cutting grinder is simple in structure, convenient to operate and high in safety, and is used for rotary cutting and grinding of uterine fibroid in laparoscopic minimally invasive operations.
Description
Technical field [0001] The invention relates to a surgical instrument, in particular to a uterine fibroids or uterine body rotary cutting pulverizer, which belongs to medical instruments. Background technique [0002] As we all know, laparoscopic subtotal hysterectomy or hysteromyomectomy has been used clinically for many years because of its small mouth and quick recovery. At present, uterine fibroids are usually used to remove or remove secondary fibroids. Whole uterus. The uterine fibroids pulverizer is usually composed of a funnel-shaped scabbard and a circular tube-shaped rotary cutting pulverizing knife located in the scabbard. The pulverizing knife can be driven by a motor to remove the fibroids by revolving the body, avoiding the long surgical incision caused by traditional open surgery. However, during the operation, the fibroids are performed without protection (that is, the revolver is performed under the condition that the fibroids specimens are completely exposed t...
