Description

Laparoscope grasping forceps

Technical Field

The utility model belongs to the field of medical equipment, specifically a peritoneoscope nipper.

Background

Laparoscopic surgery is a procedure performed using a laparoscope and its associated instruments: the cold light source is used for providing illumination, the laparoscope lens is inserted into the abdominal cavity, and the digital camera technology is used for leading the image shot by the laparoscope lens to be transmitted to a post-stage signal processing system through an optical fiber and displaying the image on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument. A laparoscope grasper is a common tool used in laparoscopic surgery to grasp and separate tissues near the surgical site during the surgery. The ordinary peritoneoscope nipper all is 2 metal binding clip, skids very easily when snatching to blood vessel and nerve near the easy damage tissue, the electric current that electrotome or electrocoagulator produced during the operation produces the injury to nerve easily, and the nipper oppresses for a long time to the tissue, can cause the irreversible damage of blood vessel, has influenced patient's postoperative healing and recovered.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a peritoneoscope nipper.

The technical scheme of the utility model as follows:

the utility model provides a peritoneoscope nipper, includes the tong pipe, and the tong pipe front portion is provided with the binding clip, and the pincers body at tong pipe rear portion is provided with fixed handle and activity handle, its characterized in that there are four binding clips, sets up respectively in the upper and lower left right position of tong pipe front portion, the binding clip is the cross when opening.

The inner side of the tong head is provided with a rubber layer.

The rubber layer is provided with a plurality of arc-shaped grooves.

And scales are arranged on the outer side of one of the tong heads.

The suction tube is arranged in the forceps tube, the suction tube is opened in the center of the front part of the forceps tube, and the suction tube penetrates through the forceps tube and the forceps body and is connected with a suction connecting device arranged at the rear part of the forceps body.

A valve is arranged at the position, close to the fixed handle, of the rear part of the suction tube and is connected with a switch arranged on the fixed handle.

The holding rings of the fixed handle and the movable handle are respectively provided with a rubber ring fixedly connected with the holding ring.

The utility model discloses a peritoneoscope nipper adopts four binding clip to rubber layer and recess on the binding clip have increased the friction, snatch the tissue more stable, reduce blood vessel and nervous pressure in the tissue, can play the effect of current protection to nerve, prevent that the electric current of electrotome etc. from causing the injury to nerve, can connect suction device simultaneously, suck away the liquid at operation position when the operation through the switch on the handle conveniently, guaranteed the operation field of vision.

Detailed Description

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

As shown in fig. 1 to 3, the utility model discloses a peritoneoscope nipper, including the

javelin

2, 2 front portions of javelin are provided with binding clip 1, and the pincers body 3 at 2 rear portions of javelin is provided with fixed handle 4 and movable handle 5, binding clip 1 has four, sets up respectively in the anterior upper and lower left and right sides position of javelin 2, and four binding clips 1 are connected with movable handle 5 through the wire rope transmission in the javelin 2, and accessible movable handle 5 controls and opens or close, is the cross when four binding clips 1 are opened. Compared with two common forceps heads, the cross-shaped forceps head 1 can grasp tissues more firmly and stably. The inner side of the tong head 1 is provided with a rubber layer 11, and the rubber layer 11 is provided with a plurality of circular arc-shaped grooves 12. Ordinary metal is compared to rubber layer 11 and recess 12, has increased the friction, and it is more stable to snatch the tissue, and reducible blood vessel and the nervous pressure in organizing simultaneously, the insulating effect of rubber can play the effect of current protection to nerve, prevents that the electric current of electrotome etc. from causing the injury to nerve.

The scale 13 is arranged on the outer side of one of the forceps heads 1, when the size of tissue needs to be measured in an operation, the tissue does not need to be taken out or other tools need to be used, and the scale 13 of the forceps head 1 only needs to be read on a laparoscope.

The interior of the forceps tube 2 is provided with a suction tube 7, the suction tube 7 is opened at the center of the front part of the forceps tube 2, and the suction tube 7 passes through the forceps tube 2 and the forceps body 3 and is connected with a suction connecting device 9 arranged at the rear part of the forceps body 3. A valve 8 is arranged at the rear part of the suction tube 7 close to the fixed handle 4, and the valve 8 is connected with a switch 10 arranged on the fixed handle 4. During operation, the suction connecting device 9 is connected with a negative pressure suction device, and the valve 8 is opened through the switch 10 on the fixed handle 4, so that liquid at the operation part can be conveniently sucked away during operation, and the operation visual field is ensured.

The rubber ring 6 fixedly connected with the holding ring is respectively arranged in the holding rings of the fixed handle 4 and the movable handle 5, so that the friction force of the hands of a doctor on the grasping forceps can be increased, the slipping during the operation is prevented, and the safety factor of the operation is increased.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
