Example 1

Referring to fig. 1 and 2, in order to illustrate a first embodiment of the present invention, this embodiment provides a pair of laparoscope auxiliary forceps, which includes a forceps body 100, including a forceps handle 101 and a forceps jaw 102, where the forceps jaw 102 is disposed at the lower end of the forceps handle 101; the housing 200, the caliper body 100 is installed inside the housing 200.

Specifically, the forceps handle 101 includes a button 101a, a disk 101b, and a cylinder 101c, the disk 101b being disposed at a lower end of the button 101a, and the cylinder 101c being disposed at a lower end of the disk 101 b.

Further, the forceps handle 101 further comprises a connecting column 101d, the connecting column 101d is arranged at the lower end of the disc 101b, and the connecting columns 101d are arranged in a plurality.

Further, the forceps handle 101 further comprises forceps arms 101e, the forceps arms 101e are symmetrically arranged at the lower end of the cylinder 101c, and arm holes 101e-1 penetrating through the forceps arms 101e are formed in the side faces of the forceps arms 101 e.

Preferably, the button 101a, the disk 101b, the cylinder 101c, the connecting post 101d and the jawarms 101e are connected to each other by welding or integrally formed.

Specifically, the jaw 102 includes an elliptical member 102a and a curved hole 102b, the curved hole 102b is disposed on the elliptical member 102a, and the elliptical member 102a is welded to the jawarm 101 e. The jaws 102 are preferably at least two so that they can be connected to two jawarms 101e for better operation.

Preferably, the corners of the oval 102a and the opening of the curved hole 102b are rounded so as not to scratch the skin of the patient during the operation of the surgeon,

when in use, a doctor performs a minimally invasive operation, slowly puts the forceps body 100 into a patient body, presses the forceps arms 101e to perform auxiliary work such as clamping in the operation process, and can also install the forceps arms into the shell 200 to perform operation in the operation process. Because the jaws 102 are rounded, the clamping does not damage the tissue of the body, and when clamped, an oval gap is formed therebetween to better secure the tissue to be resected or stapled.

Example 2

Referring to fig. 1, 2, 3, 4 and 5, a second embodiment of the present invention, which differs from the previous embodiment by a housing 200.

Specifically, the housing 200 includes a supporting column 201 and a pressing groove 202, the supporting column 201 is disposed on a side surface of the housing 200, the pressing groove 202 is disposed inside the housing 200, and the disc 101b is disposed in the pressing groove 202.

Further, the housing 200 further includes a cylindrical groove 203 and a plurality of biasing grooves 204, the cylindrical groove 203 and the plurality of biasing grooves 204 are disposed inside the housing 200, the plurality of biasing grooves 202 are communicated with the cylindrical groove 203, and the connecting column 101d is inserted into the plurality of biasing grooves 204 through the first spring 103.

The housing 200 further includes an upper slot 205 and a lower slot 206, the upper slot 205 being disposed at an upper end of the housing 200, and the lower slot 206 being disposed at a lower end of the housing 200.

The button 101a is inserted into the upper notch 205, the cylinder 101c and the clamp arm 101e are inserted into the cylindrical groove 203, and the diameter of the disc 101b is larger than that of the cylindrical groove 203, so that the disc 101b cannot be separated from the pressing groove 202 and forms a limit.

The clamp arm device further comprises a connecting pin 300, the connecting pin 300 is inserted into the arm hole 101e-1 through a second spring 301 and forms a limit relation with the clamp arm 101e, the spring 301 enables the clamp arm 101e to open, and the connecting pin 300 limits the opening distance of the clamp arm 101 e.

When the auxiliary forceps are used, a doctor performs minimally invasive surgery, only the button 101a needs to be pressed when the auxiliary forceps are used, the forceps body 100 moves downwards, the connecting column 101d extrudes the second spring 301, the jaw 102 extends out of the cylindrical groove 203, the jaw 102 can be opened under the action of the elastic force of the first spring 103, the jaw 102 is placed in the cylindrical groove 203 when not used, the jaw 102 can be opened under the action of the elastic force of the first spring 103, the jaw 102 is extruded with the inner wall of the cylindrical groove 203 and limited by the cylindrical groove 203, the size of the opening of the jaw 102 can be controlled by pressing the depth of the button 101a, and when the jaw 102 completely extends out of the cylindrical groove 203, the opening of the jaw 102 is largest. The surgical operation of the medical dental appliance requires selecting a better size of the opening of the jaw 102 for holding the tissue to be operated in the operation. When the auxiliary forceps are not needed, the first spring 103 will give an elastic force to the connecting column 101d by simply releasing the button 101a, so that the forceps handle 101 moves to return to the original position, and the jaws 102 return to the cylindrical groove 203. At present, the incision of the minimally invasive surgery is smaller and smaller, the incision of the traditional laparoscopic surgery is generally 5mm or 10mm or even larger, the auxiliary operation is difficult to realize by using the existing poking clamp and operating clamp, and the length of the clamp arm 101e and the shell 200 of the device can be customized according to the requirement so as to be convenient for better assisting a doctor in the operation in the minimally invasive surgery. The device does not need external force for clamping, so that the device can be made very small to meet the requirements of minimally invasive surgery, and can play a good auxiliary role to achieve the aim of more minimally invasive surgery treatment.
