The purpose of the utility model is to overcome the defects of the prior art, provide a kind of needle forceps, by changing needle forceps Tong head feature, with improve sewing needle clamping stability.

To achieve the above object, the utility model proposes following technical solutions: clamping including the first caliper and with described first The second connected caliper of body, first caliper include the first binding clip, the first clamp handle, and connection first binding clip and described First claw beam of the first clamp handle, first binding clip is vertical with first claw beam, and first claw beam is the hollow body of rod, and It is connected one end with first binding clip with an opening, the second caliper sliding passes through first claw beam to the opening And the first binding clip cooperation is to clamp sewing needle.

Preferably, second caliper includes the second claw beam and the second handle hinged with second claw beam, and described Two claw beams pass through first claw beam and are slidably connected with first claw beam.

Preferably, second claw beam is equipped with tabletting close to one end of first binding clip, and the tabletting protrudes from described The outer rim of second claw beam.

Preferably, the end face of relatively described second binding clip of first binding clip is equipped with plural teeth, and the teeth are laterally set It sets on the end face of second binding clip and is arc.

Preferably, second clamp handle is hinged by the first pin shaft with first claw beam, passes through with second claw beam Second pin shaft is hinged.

Preferably, first claw beam is equipped with the fin for sliding for second claw beam, and second claw beam is equipped with With the matched groove of the fin.

Preferably, first caliper is integrated injection molding.

The contact surface when binding clip for increasing needle forceps and sewing needle of the utility model clamp makes needle forceps clamping suture Needle is more stable and firm, is not easy to slide.

Specific embodiment

Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete Description.

Referring to figs. 1 and 2, the revealed needle forceps of the utility model, for during surgery to the wound of patient into Row suture.Including the first caliper 1 and the second caliper 2, the second caliper 2 is connected with the first caliper 1 and under external force first 1 internal slide of caliper realizes the first caliper 1 and the second caliper 2 clamping sewing needle by sliding.

Specifically, the first caliper 1 includes the first binding clip 11, the first clamp handle 13, and the first binding clip of connection 11 and the first pincers First claw beam 12 of handle 13, three in one injection molding.Wherein the first binding clip 11 is vertical with the first claw beam 12 connect, the first claw beam 12 be the hollow body of rod, and one end for being connected with the first binding clip 11 of the first claw beam 12 is equipped with one and is open 23, and the second caliper 2 is across the One claw beam 12 simultaneously reaches at opening 23, and the second caliper 2 can slide in the first claw beam 12.Pass through the sliding of the second caliper 2 So that a conjunction is opened in the front end one of the first binding clip 11 and the second caliper 2, sewing needle a part is placed on can be by first at opening 23 The clamping of the front end of binding clip 11 and the second caliper 2.And the clamping due to sewing needle by three angles, not only increase sewing needle folder Fastness is held, while preventing sewing needle from falling off, brings difficulty to surgical procedure.

Further, the second caliper 2 include the second claw beam 21 and the second handle 22 hinged with the second claw beam 21, second Claw beam 21 passes through the first claw beam 12 and is slidably connected with the first claw beam 12.As shown in Figure 1, the second claw beam 21 is close to the first binding clip 11 One end is equipped with tabletting 221, and tabletting 221 protrudes from the outer rim of the second claw beam 21.Cooperated by tabletting 221 with the first binding clip 11 to press from both sides Sewing needle is held, since tabletting 221 protrudes from the outer rim of the second claw beam 12, is easier to clamp when clamping sewing needle.

Further, as shown in Fig. 2, the end face of opposite second claw beam 21 of the first binding clip 11 is equipped with plural teeth 111, teeth 111 are horizontally installed on the end face of the first binding clip 11 and are arc.Sewing needle can be placed in the teeth 111 of arc, be made in this way Obtain the stronger of sewing needle clamping.

Preferably, the second clamp handle 22 and the first claw beam 12 are hinged by the first pin shaft 3, the second clamp handle 22 and the second claw beam 21 It is hinged by the second pin shaft 4.When user moves up and down the second clamp handle 22, the second clamp handle 22 is fulcrum with the first pin shaft 3, and It pushes the second claw beam 21 to move horizontally by the second pin shaft 4, and then realizes the folding of the second claw beam 21 and the first binding clip 11.

Preferably, the first claw beam 12 is equipped with the fin (not shown) for sliding for the second claw beam 21, and the second claw beam 21 is set Have and the matched groove (not shown) of fin.The cooperation of fin and groove is equivalent to dragging track, makes the second claw beam 21 in fixation Sliding on rails, play the role of limit.

The utility model has structure simple, and improves the fastness of needle forceps clamping sewing needle in clamping sewing needle, It avoids sewing needle unstable because clamping due to slipping phenomenon occurs, improve the working efficiency of doctor.

The technology contents and technical characteristic of the utility model have revealed that as above, however those skilled in the art still may be used Can teaching based on the utility model and announcement and make various replacements and modification without departing substantially from the spirit of the present invention, therefore, this Utility model protection range should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model And modification, and covered by present patent application claim.
