Embodiment 1

[0050] Such as figure 1 , figure 2 As shown, this embodiment provides a gas jet stripping electric cutting head, including a metal pipe body 1 with a gas flow channel 4 inside, one end of the metal pipe body 1 is closed, and the other end is provided with an air inlet port communicating with the gas flow channel 4 2. There is an outlet port 3 communicating with the gas flow channel 4 at the closed part of the metal tube body 1 or / and on the outer wall of the metal tube body 1 close to the closed part of the metal tube body 1; the inner diameter of the gas flow channel 4 is determined by the inlet The gas port 2 gradually decreases or decreases stepwise toward the gas outlet port 3; the specific scheme of this implementation is that a gas outlet connected to the gas flow channel 4 is provided on the outer wall of the metal tube 1 close to the closed part of the metal tube 1. port 3.

[0051] In the present invention, one end of the metal pipe body 1 is closed, and the other ...

Embodiment 2

[0071] Such as Figure 8 As shown, the metal pipe body 1 in the present invention is an improvement on the basis of the first embodiment. The technical content disclosed in the first embodiment will not be described repeatedly, and the content disclosed in the first embodiment also belongs to the content disclosed in this embodiment.

[0072] The longitudinal section of the connecting section 101 in this embodiment is square.

[0073] In the present invention, the longitudinal section of the connecting section 101 is designed to be square to ensure the air intake of the metal pipe body 1 and ensure the effective separation of organs. At the same time, the longitudinal section of the connecting section 101 is designed to be rectangular, which is convenient for processing. The section can be rectangular or square.

Embodiment 3

[0075] The difference between the present embodiment and the first embodiment lies only in the opening position of the air outlet port 3. The technical content disclosed in the first embodiment will not be described repeatedly, and the content disclosed in the first embodiment also belongs to the content disclosed in this embodiment.

[0076] Such as Figure 9 As shown, this embodiment provides a gas jet stripping electric cutting head, including a metal pipe body 1 with a gas flow channel 4 inside, one end of the metal pipe body 1 is closed, and the other end is provided with an air inlet port communicating with the gas flow channel 4 2. There is an outlet port 3 communicating with the gas flow channel 4 at the closed part of the metal tube body 1 or / and on the outer wall of the metal tube body 1 close to the closed part of the metal tube body 1; the inner diameter of the gas flow channel 4 is determined by the inlet The gas port 2 gradually decreases or decreases stepwise to...

Abstract

The invention relates to the technical field of surgical instruments, in particular to a jet stripping electric resection head and a jet stripping electric resection device. The jet stripping electricresection head comprises a metal pipe body internally provided with a gas channel, one end of the metal pipe body is closed, a gas inlet end port communicating with the gas channel is formed in the other end of the metal pipe body, and a gas outlet end port communicating with the gas channel is formed in the outer side wall, at the closed position of the metal pipe body or / and close to the closedposition of the metal pipe body, of the metal pipe body; the inner diameter of the gas channel gradually decreases or decreases in a stepwise mode from the gas inlet end port to the gas outlet end port; the structure design of the jet stripping electric resection head achieves that the flow rate of gas when the gas is ejected from the gas outlet end port is increased, the gas with certain kineticenergy is ejected to facilitate separation of the deep part of an abdominal cavity and tissue organs which tightly adhere one another; and potential gaps in the abdominal cavity can be blown open; and an efficient, accurate and safe laparoscopic surgical instrument for an operator is provided.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to an air jet stripping electric cutting head and an air jet stripping electric cutting device. Background technique [0002] Laparoscopic surgery is the use of laparoscope and related instruments for abdominal diseases. In order to have enough space for laparoscopic surgery, it is necessary to continuously perfuse the abdominal cavity with carbon dioxide gas to establish artificial pneumoperitoneum, which is a necessary condition for laparoscopic surgery. [0003] However, existing equipment can only infuse gas into the abdominal cavity, and in laparoscopic surgery, when dissecting deep abdominal viscera, the side or back of tissue viscera, or inflamed viscera and surrounding tissues When there are tight adhesions between them and need to be separated, or when the dissected organs are surrounded by important blood vessels, nerves and other tissues, the existing laparo...
