Abstract

The utility model provides special pliers used for taking-up an implanting silicon gel bar under skin, which is composed of two pliers bodies; the two pliers bodies are connected via an axle pin; the pliers bodies are divided into clamping ends and plier handles; the end portion of the engagement surface of the clamping end is designed with two engagement gears; the positions of fours engagement gears of the two clamping ends are relative. Due to the fact that the special pliers used for taking-up an implanting silicon gel bar under skin adopts the engagement method that the engagement gears whose clamping is non-planar, even if the clamping of the aged implanting silicon gel bar under skin is caused to be hard to be broken; the operative time is reduced, the operative difficulty is reduced, the use is simple and the operation is simple.

Description

Subdermal implants silica gel stick dedicated fixed pincers

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially a kind of fixation clamps of special use when taking out the subdermal implants silica gel stick.

Background technology

Utilizing subdermal implants to practise contraception is a kind of new contraceptive device that grows up gradually in the world in recent years, owing to have efficient, long-term, easy and advantage such as can repeat to be suitable for, welcome by the women of child-bearing age.At present, the I type that is mainly, the II type subdermal implants of using clinically.After severe complication occurring or arriving the operating period, all need to take out as foreign body.When taking out the implants silica gel stick, adopt outside the common mosquito forceps clamping and take out.Common mosquito forceps end is concordant, only parallel groove is arranged, easy slippage during clamping in the engaging piece design; Simultaneously because silica gel stick is aging for a long time, be easy to during gripping cracked, thereby when causing performing the operation hemorrhage many, the time long, painful big, the operation receiveing person is difficult to acceptance.

Summary of the invention

The purpose of this utility model provides a kind of effectively fixedly subdermal implants silica gel stick, and dedicated fixed that can safety quick taking-up silica gel stick pincers.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of dedicated fixed pincers that are used to take out the subdermal implants silica gel stick, it is made of two calipers, two calipers connect by pivot pin, caliper is divided into bare terminal end and pincers handle, it is characterized in that: the termination portion design on the occlusal surface of bare terminal end has two tooth engaged, and four tooth engaged positions of two bare terminal ends are relative.When the tooth engaged interlock, can form an enclosed space between the tooth engaged, the sectional dimension of this space and implants silica gel stick adapts.

Because this utility model has adopted the engaging tooth interlock mode of on-plane surface clamping, even also be difficult for when making aged implants silica gel stick clamping brokenly, reduced operating time by folder, reduced the difficulty of operation, easy to use, simple to operate.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Embodiment 1

The dedicated fixed pincers that are used to take out the subdermal implants silica gel stick as shown in Figure 1, it is made of two calipers, two calipers connect by pivot pin, caliper is divided into bare terminal end 2 and pincers handle 3, termination portion design on the occlusal surface of bare terminal end 2 has four tooth engaged positions of two tooth engaged 1, two bare terminal ends relative.When tooth engaged 1 interlock, can form an enclosed space between the tooth engaged, the sectional dimension of this space and implants silica gel stick adapts.

Other similar structure also can be arranged on embodiment of the present utility model; as can be in the fixedly connected semicircular ring of the occlusal termination of bare terminal end portion; can constitute a circular cavity during two semicircular ring interlocks in order to clamping implants silica gel stick, the conversion of this similar structures should be considered as being included within the protection domain of the present utility model.

Claims

1, a kind of dedicated fixed pincers that are used to take out the subdermal implants silica gel stick, it is made of two calipers, two calipers connect by pivot pin, caliper is divided into bare terminal end (2) and pincers handle (3), it is characterized in that: the termination portion design on the occlusal surface of bare terminal end (2) has two tooth engaged (1), and four tooth engaged positions of two bare terminal ends are relative.
