Description

Minimally invasive abdominal tissue resectoscope

Technical Field

The invention belongs to the technical field of surgical resection instruments, and particularly relates to a minimally invasive abdominal tissue resectoscope.

Background

The minimally invasive surgery is performed by using the existing medical instruments and related equipment such as a laparoscope, a thoracoscope and the like, the minimally invasive surgery does not need to be performed, a doctor opens 1-3 small holes of 0.5-1.0cm on a patient, the minimally invasive surgery instruments go deep into the focus part of the patient through the small holes, and the surgery is completed outside the patient body by controlling the instruments. The minimally invasive surgery has small wound, the body function of the patient after the surgery can be recovered quickly, the hospitalization time of the patient is shortened, the harm of the traditional surgery to the human body is reduced, and the pain of the patient is greatly relieved.

In general, a minimally invasive surgery is generally performed by cutting a lesion tissue with a surgical cutting instrument, and then taking out the lesion tissue after the cutting is completed. Can not realize the excision and the extraction of the lesion tissues at the same time, and has long operation time. In order to shorten the operation time and relieve the pain of a patient, a device capable of cutting and taking out the diseased tissue simultaneously is provided.

Disclosure of Invention

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1 and 2, the minimally invasive abdominal tissue resectoscope disclosed by the present invention comprises a rod body 1, a transmission assembly 2, a resection assembly 3 and a receiving device 5. The section of the rod body 1 is circular, a handle 4 is arranged at one end of the rod body 1, the handle 4 comprises a fixed handle 41 and a movable handle 42, the fixed handle 41 is fixedly connected with the rod body 1, and the transmission assembly 2 is hinged to the movable handle 42. The transmission assembly 2 and the storage device 5 are arranged inside the rod body 1, and the cutting assembly 3 is connected with the transmission assembly 2. During the operation, the handle 4 of the 1 one end of the body of rod of handheld, with the body of rod 1 other end go deep into patient's abdominal cavity, reach pathological change position, excision subassembly 3 is amputated patient's pathological change tissue. The excision subassembly 3 brings the pathological change tissue that cuts off into storage device 5, takes out the pathological change tissue that cuts off from the patient in the time of accomplishing the pathological change tissue excision, shortens operation time, alleviates patient's misery.

As shown in fig. 2, the transmission assembly 2 includes a guide rod 21 hinged to the movable handle 42 and a connection ring 22 fixedly connected to the guide rod 21, the guide rod 21 and the connection ring 22 are coincident with the axis of the rod body 1, and the guide rod 21 and the connection ring 22 slide along the inner wall of the rod body 1.

As shown in fig. 2, the cutting assembly 3 includes a movable blade 31 and a housing 32, and the housing 32 is a hemispherical shell with an opening facing one end of the handle 4 and fixedly connected to the connecting ring 22. The movable blade 31 is fixedly connected with the housing 32 and the connecting ring 22, and the side of the movable blade facing the handle 4 is the blade side. The spherical arrangement of the shell 32 can avoid the damage to other tissues in the abdominal cavity of the patient when the exciser enters the abdominal cavity of the patient and the lesion part is searched.

As shown in fig. 2 and 3, the storage device 5 includes a row cutting pipe 51, the row cutting pipe 51 is fixedly connected to the inner wall of the rod body 1, and one end of the row cutting pipe 51 extends out of the rod body 1. One end of the row cutting pipe 51 close to the movable blade 31 is fixedly connected with a row cutting grid 52, the row cutting grid 52 is in a spherical shell shape, and the row cutting grid 52 is provided with a blade edge which faces one side of the movable blade 31. One side of the row cutting grid 52 close to the handle 4 is fixedly connected with a non-return baffle plate 53 (see fig. 4), the middle of the non-return baffle plate 53 is provided with a cross-shaped opening, one side of the shell 32 close to the row cutting pipe 51 is fixedly connected with a push block 33 matched with the row cutting grid 52, and the push block 33 is in clearance fit with the row cutting grid 52. When the housing 32 is engaged with the row-cutting grid 52, the pusher 33 pushes the lesion tissue into the row-cutting tube 51 through the row-cutting grid 52, and the non-return flap 53 prevents the small pieces of lesion tissue from being re-introduced into the patient. An elastic storage bag 54 is sleeved on the opening of the row cutting pipe 51 on the outer side of the rod body 1, and a support frame 55 for supporting the elastic storage bag 54 is fixedly connected to the rod body 1.
