Abstract

The utility model relates to a pair of oral operating forceps used in an oral maxillofacial surface department. The operating forceps comprise finger holding rings, a forceps handle and a forceps arm, the forceps handle is connected with the finger holding ring fixedly, a forceps mouth is fixedly arranged at the front end of the forceps arm, the forceps arm is formed by plugging a front-section forceps arm and a rear-section forceps arm, and the rear-section forceps arm and the forceps handle are connected by a pin shaft; and teeth and spaces which are fitted are arranged at the clamping part of the forceps mouth. When being used for clamping the front edge of a mandible ascending limb, the oral operating forceps are clear in eyesight, and beneficial to conduction of an oral operation, the operation time is shortened, and the pain of a patient can be relieved.

Description

A kind of oral cavity forceps

Technical field

This utility model relates to a kind of medical surgical instrument, particularly the used oral cavity forceps of oral and maxillofacial surgery section.

Background technology

Oral cavity forceps is the apparatus commonly used in the decorative sursery operation, is mainly used in the sclerous tissueses such as clamping jawbone.The orthognathic surgery in oral cavity is place's important branch and a new branch of science of Oral and Maxillofacial Surgery; orthognathic surgery is more and more carried out at national various big hospital; sagittal split ramus osteotomy is one of art formula the most frequently used in the orthognathic surgery; in this operation; operating forceps is mainly used in clamping mandibular ramus leading edge; stop soft tissue and the bicker of ascending branch leading edge, be conducive to surgical field of view and expose, also can protect surrounding soft tissue to avoid damage simultaneously.Because orthognathic surgery carries out in inside, oral cavity fully, often need to use osteotome, osteotome and various jawbone power apparatus, the working place is extremely limited, therefore structure and the operating characteristics thereof of operating theater instruments are had higher requirements, and the oral cavity forceps that uses now since between tong arm and clamp handle angle can't adjust, and the length of tong arm is changeless, the position of clamp handle and finger gripping ring can not all be in outside the surgical field of view, take space limited in the oral cavity, be unfavorable for operation technique.

Summary of the invention

In order to address the above problem, this utility model provides a kind of oral cavity forceps.Angle between this oral cavity forceps tong arm and clamp handle and tong arm length all can be adjusted according to the actual needs of operation, the position of clamp handle and finger gripping ring can not all be in outside the surgical field of view, in clamping mandibular ramus leading edge, can effectively stop soft tissue and the bicker of ascending branch leading edge, do not need other para-operational device, be conducive to the operation of operation on oral cavity.

The technical solution of the utility model is: a kind of oral cavity forceps, comprise finger gripping ring and the clamp handle and the tong arm that are fixedly connected with the finger gripping ring, the front end fixation clamps beak of tong arm, wherein, described tong arm is leading portion tong arm and two sections grafting of back segment tong arm, and is connected by bearing pin between described back segment tong arm and clamp handle.

In addition, the retaining part of described pincers beak is that the tooth that matches cooperates with groove.

The beneficial effects of the utility model are: owing to adopt technique scheme, angle between this oral cavity forceps tong arm and clamp handle and the length of tong arm all can be adjusted according to the actual needs of operation, the position of clamp handle and finger gripping ring is in outside the surgical field of view, thereby avoid the impact on operation technique, simultaneously can avoid again clamp handle to osteotome, the interference of other operating theater instruments such as osteotome, operation doctor's actual needs when performing the operation to satisfy, in clamping mandibular ramus leading edge, can effectively stop soft tissue and the bicker of ascending branch leading edge, do not need other para-operational device, reduce disturbance, be conducive to the operation of operation on oral cavity, shorten operating time, reduce patient's misery.

Description of drawings

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

Fig. 2 is the local enlarged diagram of sequence number pincers beak 6 among Fig. 1.

1-finger gripping ring among the figure, the 2-clamp handle, the 3-bearing pin, 4-back segment tong arm, 5-leading portion tong arm, 6-clamps beak, 7-baffle plate.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, this oral cavity forceps, comprise clamp handle 2 and tong arm that finger gripping ring 1 and finger gripping ring are fixedly connected with, the front end fixation clamps beak 6 of tong arm, wherein, described tong arm is leading

portion tong arm

5 and 4 two sections grafting of back segment tong arm, can adjust entire length, and 2 of described back segment tong arm 4 and clamp handles be connected by bearing pin 3, so that the angle between tong arm and clamp handle can be 0 ⁰～60 ⁰Between regulate, the position of clamp handle and finger gripping ring is in outside the surgical field of view, operation doctor's actual needs when satisfying operation, thereby avoid impact on operation technique; Because there is baffle plate 7 in the pincers beak outside, in clamping mandibular ramus leading edge, can effectively stop soft tissue and the bicker of ascending branch leading edge simultaneously, thereby avoid clamp handle to the interference of other operating theater instruments such as osteotome, osteotome, be conducive to shorten operating time, reduce patient's misery, as shown in Figure 1.

In addition, in order firmly to clamp the mandibular ramus leading edge, the retaining part of described pincers beak 6 is that the tooth that matches cooperates with groove, makes clamping firm, as shown in Figure 2.

Angle between this oral cavity forceps tong arm and clamp handle and the length of tong arm all can be adjusted according to the actual needs of operation, the position of clamp handle and finger gripping ring is in outside the surgical field of view, thereby avoid the impact on operation technique, simultaneously can avoid again clamp handle to osteotome, the interference of other operating theater instruments such as osteotome, operation doctor's actual needs when performing the operation to satisfy, in clamping mandibular ramus leading edge, utilize the pincers beak outside to have baffle plate 7 can effectively stop soft tissue and the bicker of ascending branch leading edge, do not need other para-operational device, reduce disturbance, be conducive to the operation of operation on oral cavity, shorten operating time, reduce patient's misery.

Claims
