Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a hemostatic forceps for obstetrics and gynecology department, which comprises a forceps head 1 and a drill bit 2. The forceps head 1 comprises a left forceps jaw 1a, a right forceps jaw 1b, a pin shaft 7 and a coil spring 6, wherein the left forceps jaw 1a and the right forceps jaw 1b are hinged together through the pin shaft 7 and form a two-flap split structure. A coil spring 6 is wound on the pin shaft 7 and is arranged between the left jaw 1a and the right jaw 1b, and the normally open state of the binding clip 1 is realized by the coil spring 6.

The spring 6 realizes that the binding clip 1 is in a normally open state: the coil spring 6 provides an elastic force in the circumferential direction of the pin shaft 7, by which the left and

right jaws

1a and 1b are spread apart. Under the condition that no other structure limits the left clamp 1a and the right clamp 1b, the left clamp 1a and the right clamp 1b are in a relatively repulsive state, that is, the clamp head 1 is in a normally open state in the present case. It should be noted that the mounting structure of the coil spring 6 is not essential to the invention of the present application, and may be any structure of a spring clip in the prior art.

The caliper body comprises a sleeve 2a and a pull rod 2 b. The sleeve 2a is hollow and cylindrical, and the pull rod 2b is in sliding fit with the hollow cavity of the sleeve 2a along the axial direction. The upper end of the pull rod 2b is positioned in the hollow cavity of the sleeve 2a, and the upper end of the pull rod 2b is fixedly connected with the left clamp 1a or the right clamp 1 b. In this case, the tie rod 2b may be riveted to the left jaw 1a, or may be riveted to the other jaw. The pull rod 2b provides axial tension along the sleeve 2a for the tong head 1, and when the pull rod 2b is pulled to move towards the direction far away from the tong head 1, the tong head 1 is extruded by the cavity in the sleeve 2a and then is closed. Therefore, in the present application, the outer side walls of the left jaw 1a and the right jaw 1b close to the tail of the pin 7 are both in sliding fit with the sleeve 2 a.

As shown in fig. 1, the lower end of the pull rod 2b is located outside the sleeve 2a, and a second handle 5 is fixed to the lower end of the pull rod 2 b. The outer side wall of one end of the sleeve 2a close to the second handle 5 is fixed with a first handle 3, the first handle 3 extends towards the outside of the sleeve 2a, and the first handle 3 is mainly used for being pulled by fingers of a doctor. A pressure spring 4 is arranged between the first handle 3 and the second handle 5, the pressure spring 4 is sleeved on the pull rod 2b, and the pressure spring 4 is used for providing axial tension of the pull rod 2 b.

According to the structure, the following components are adopted: in an initial state, the pressure spring 4 presses the axial direction of the pull rod 2b to push the first handle 3, the first handle 3 pushes the pull rod 2b to move along a direction far away from the binding clip 1, and meanwhile, the pull rod 2b pulls the binding clip 1 to retract towards the hollow cavity of the sleeve 2 a. The tong head 1 is pressed by the port of the sleeve 2a to realize a normally closed state.

The state when in use: when the pliers is used, fingers of a doctor are buckled on the first handle 3, the second handle 5 is held by the palm, then the first handle 3 and the second handle 5 are pressed forcibly, the pull rod 2b is enabled to slide axially along the sleeve 2a towards the direction of the gripping head, the pliers head 1 extends towards the outside of the sleeve 2a, and the pliers head 1 is opened under the action of the coil spring 6. And once the doctor releases the fingers, the forceps head 1 is restored to the initial state, and the forceps head 1 is closed.

The above implementation process is that the forceps head 1 completes the opening and closing process, but in the specific use process, the drill bit 2 extends into the body of a patient, and the sleeve 2a inevitably contacts with the skin tissue in the body of the patient. In order to guarantee sleeve 2 a's structure, improve patient's comfort level again, in the present case, sleeve 2a can adopt the higher material of intensity such as stainless steel, duroplast, but suit one deck silica gel layer 9 on sleeve 2 a's lateral wall, utilize the contact of silica gel layer 9 and patient's skin tissue like this, can enough prevent to cause the damage to patient's skin tissue, can improve patient's comfort level again.

In order to prevent liquid in the patient from entering the interior of the sleeve 2a, the sleeve 2a is not easily cleaned. In the scheme, an annular groove is formed in the hollow cavity of the sleeve 2a along the axial direction, a sealing ring 8 is fixedly clamped in the annular groove, and the inner ring of the sealing ring 8 is attached to the outer wall of the pull rod 2 b. The advantages of such an arrangement are: the liquid of the patient is prevented from entering and flowing out of the gap between the pull rod 2b and the sleeve 2 a. Namely, the sealing ring 8 is used for sealing the gap between the pull rod 2b and the sleeve 2a in the bracket.
