Abstract

The utility model discloses a safety net basket matched with a tissue pulverizer, which comprises an outer sheath, a handle, and a net basket. The net basket is connected with the tissue pulverizer, and the capacity of the net basket is any one of 100ml, 150ml or 200ml. The utility model places the tissue specimen inside the net basket in advance, and the position is relatively fixed, so the time for searching for the tissue specimen is greatly shortened. At the same time, with the protection of the safety net basket, the secondary damage to surrounding organs such as the bladder and bowel canal is avoided during the tissue crushing process, which reduces the risk of surgery. It can effectively block and prevent the net basket from being sucked into the cutter head of the shredder at the same time, which increases the applicability.

Description

A safety net basket matched with a tissue shredder

technical field

The utility model relates to the technical field of tissue shredders, in particular to a safety net basket matched with the tissue shredder.

Background technique

Minimally invasive technology has become the most important and commonly used method in surgical operations. In order to minimize surgical wounds, tissue morcellators are used in minimally invasive operations for certain benign diseases. Currently, the commonly used tissue morcellators can be used The natural orifice, such as the urethra or the operating channel of the laparoscope, is placed in the surgical area, and the resected tissues or organs are pulverized and sucked out of the body, such as the prostate after enucleation of the prostate and the fibroids after uterine fibroids, so as to maximize the The surgical incision is reduced, and the minimally invasiveness is "extreme". Although the tissue morcellator can more efficiently shatter the surgically resected tissue specimens, it has the following two disadvantages: (1) The cutter head of the tissue morcellator also has a negative impact. There are two functions of pressure suction and rotary cutting to crush tissue. The knife head sucks and grinds the tissue specimen through negative pressure during work. A little carelessness may suck the nearby bladder, intestinal tract and other organs into the knife head and crush it, resulting in serious surgery. Complications, which is also the most important reason for the limited clinical use of tissue morcellators at present; (2) The resected tissue samples are generally free in the abdominal cavity or bladder cavity. Afterwards, it will take some time before the specimen can be found and the crushing work will be started, which increases the operation time and the trauma of the patient accordingly.

Therefore, in order to overcome the deficiencies of the above-mentioned technologies, a tissue comminution that can effectively block adjacent organs, avoid surgical side damage, and eliminate the need for tissue morcellators to find tissue samples in the surgical area, greatly shortening the operation time The safety net basket that device is matched with is exactly the problem that the inventor will solve.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of this utility model is to provide a safety net basket for a tissue morcellator. The link of looking for tissue samples in the operation area greatly shortens the operation time.

The technical solution adopted by the utility model to solve its technical problems is: a safety net basket for supporting the tissue pulverizer, which includes a safety net basket, and the safety net basket includes an outer sheath, a handle, and a net basket. The net baskets are connected, the handle is covered with an outer sheath, and the net basket can be received or sent out of the sheath, and the safety net basket is connected with the tissue grinder.

Further, the capacity of the net basket is any one of 100ml, 150ml or 200ml.

The beneficial effects of the utility model are:

1. In this utility model, the tissue specimens are placed inside the net basket in advance, and the position is relatively fixed, so the time to find tissue specimens is greatly shortened. At the same time, with the protection of the safety net basket, the bladder and intestinal tubes are avoided during the tissue crushing process. The secondary damage to the surrounding organs reduces the risk of surgery.

2. Through the fine mesh design of the mesh basket, the utility model can not only effectively block the adjacent organs of the surgical specimen, but also avoid sucking the mesh basket into the cutter head of the pulverizer at the same time, which increases the applicability.

detailed description

The utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

Referring to Fig. 1 is a schematic diagram of the structure of the utility model, referring to Fig. 2 is a schematic diagram of the state of the net basket of the utility model received in the outer sheath, the structure is a safety net basket for supporting a tissue pulverizer, which includes an outer sheath 1, a handle 2, and a net basket 3. The handle 2 is connected with the mesh basket 3, and the handle 2 is covered with a hollow outer sheath 1. By pushing and pulling the handle 2, the mesh basket 3 can be freely received or sent out of the outer sheath 1, and the safety mesh basket is connected with the tissue morcellator.

The capacity of the mesh basket 3 is any one of 100ml, 150ml or 200ml to meet the needs of different operations. During the operation, after the tissue sample is removed, the safety net basket can be placed into the abdominal cavity or the bladder cavity through the operating channel (Troca) of the laparoscope or the cystostomy channel, and the net basket 3 is sent out by pushing the handle 2 The outer sheath 1 puts the resected tissue specimen into the mesh basket 3, and then puts the tissue morcellator cutter head through another channel (usually there are 2-4 operating channels in laparoscopic surgery), and the tissue morcellator cutter head is safely The tissue crushing process is completed in the mesh basket. The fine mesh design of the mesh basket 3 can not only effectively block the organs adjacent to the surgical specimen, but also prevent the mesh basket 3 from being sucked into the morcellator head at the same time, which increases the applicability.

Because the utility model has placed the tissue specimen inside the net basket 3 in advance, the position is relatively fixed, so the time for the knife head of the tissue morcellator to find the tissue specimen is greatly shortened, and the operation time is reduced. More importantly, with the net basket 3 In the process of tissue comminution, secondary damage to surrounding organs such as the bladder and intestines is basically avoided, reducing the risk of surgery.
