Abstract

The utility model provides a pneumoperitoneum needle for abdominal operations, which is used for injecting carbon dioxide gas into the abdominal cavity. The pneumoperitoneum needle for abdominal operations comprises a needle tube, an outer tube, a core rod and a valve body, wherein, the outer tube and the needle tube are fixedly connected; the hollow core rod penetrating through the needle tube is connected with the valve body whose centre is provided with a hole; a valve core with a hole is arranged in the valve body and controlled to rotate by a handle and a fastening block for communicating or blocking the hole of the valve core with the hole arranged in the centre of the valve body. The front end of the core rod is provided with a blunt end. When the pneumoperitoneum needle for abdominal operations is used, firstly, the blunt end contacts the skin and retracts into the needle tube; after the needle tube is inserted into the abdominal cavity, the blunt end can be sprung automatically, and the carbon dioxide gas is injected into the abdominal cavity. The utility model has the advantages that structure is simple, the operation is easy, the pain on operated patients is alleviated, and the complication can be prevented to be created. The pneumoperitoneum needle for abdominal operations is a necessary appliance for abdominal operations.

Description

Pneumoperitoneum needle for abdominal operation

This utility model abdominal operation pneumoperitoneum pin, it relates to a kind of surgical operation apparatus.

For many years, surgical operation such as gallbladder removal etc. all is an abdominal, and the shortcoming of this operation stays the ugly cicatrix except causing stomach wall, and incision pain is brought very big misery to the patient, makes many patients forbidding to operative treatment, and even steps back.Owing to the wound or the infection of incision of abdominal wall, increased patient's extra misery, even produced a series of complication relevant in addition with otch.

For overcoming the shortcoming that above-mentioned prior art exists, this utility model provide a kind of can be across the abdominal operation that patient's belly undergos surgery pneumoperitoneum pin, it is in order to obtain the open visual field and sufficient space, avoid intestinal tube in operating process, to damage, before operation, inject about 5 liters CO earlier by the pneumoperitoneum pin to intraperitoneal ₂Gas.

The purpose of this utility model realizes by following measure: the pneumoperitoneum pin is made up of needle tubing, plug, outer tube and valve body, the valve body center is porose, the tubular portion of front end inserts outer tube, the outer tube front end is fixedlyed connected with needle tubing, the needle tubing termination is the inclined-plane, hollow plug is housed in the pipe, and plug one end is connected with valve body, and the other end is blunt nosed and exposes the needle tubing termination; Be provided with inner nut, spring and clamping screw between the insertion portion of outer tube and valve body; Spool is housed in the valve body, has the lateral aperture that communicates with the valve body centre bore on the spool, the spool top is provided with handle, and spring and the nut that is connected with valve body are arranged at the bottom, and the fixture block of restriction handle slewing area is housed on the valve body.

Description of drawings is as follows:

Fig. 1 is abdominal operation pneumoperitoneum needle construction sketch map

1-needle tubing 2-outer tube 3-plug 4-valve body 5-inner nut among the figure

6-spring 7-clamping screw 8-spool 9-fixture block 10-handle

11-spring 12-nut

Below in conjunction with accompanying drawing this utility model is further described: referring to Fig. 1, there is needle tubing (1) in the place ahead of abdominal operation pneumoperitoneum pin, it is fixedlyed connected with outer tube (2), its termination is the inclined-plane, the tubular portion of valve body (4) front end inserts outer tube (2), be provided with inner nut (5) between its insertion portion and the outer tube (2), spring (6) and clamping screw (7), there is through hole at valve body (4) center, spool (8) is housed in the valve body, has the lateral aperture that is connected with the valve body centre bore on the spool, handle (10) is established at spool (8) top, and spring (11) is established in the bottom, and the nut of spring outside (12) is connected with valve body; Installing hollow plug (3) in the needle tubing (11), one end and valve body (4) join, and the other end is blunt nosed; Valve body (4) is gone up installing fixture block (9), with the slewing area of its joystick (10).During use, with pneumoperitoneum pin rear end and CO ₂Gas output tube connects, turning handle (10) makes the hole on the spool (8) be communicated with the centre bore of valve body (4), when the blunt nosed contact skin of plug (3), blunt nosed pressurized retraction needle tubing (1), while holddown spring (6), meanwhile, the beveled tip of needle tubing (1) is pricked into skin, after needle tubing (1) entered the abdominal cavity, plug (3) is blunt nosed to expose needle tubing (1), CO automatically with the resilience of spring (6) ₂Gas enters the abdominal cavity by the pneumoperitoneum pin.Work as CO ₂After gas reached and needs quantity, turning handle (10) staggered the hole on the spool (8) and the hole at valve body center, and the pneumoperitoneum pin hole is closed.The pneumoperitoneum pin extracted use perforator instead.

The utility model compared with prior art has the following advantages: simple in structure, easy for operation, alleviate the patient suffering, avoid producing various postoperative complications.
