Abstract

The utility model relates to a steel wire guiding inner fixed pincer, the body of which comprises a head part, a combination part and a holding part, the head part of the pincer contains a steel wire guiding channel within, which is capable of the passing through of the steel wire, two ends of the channel are respectively opening on the head side surface and the head occlusal surface, channel opens of two side engagement ends are anastomotic. After the open reduction of the fracture, the inner fixing pincer bypasses the backbone, following the occlusion of the inner fixing pincer, the steel wire is guided from one side of the end of the pincer head part through the channel opening to enter, goes along the guiding channel, bypasses the backbone and comes out from the other side of the channel, then the occlusion part of the pincer head is released, the steel wire guiding inner fixing pincer is withdrawn and occlusal, when the steel wire bypasses the backbone for one cycle and butt joints with the occlusion part, the holding part of the pincer body is tightly held and the pincer body is rotated, to complete the fracture steel wire inner fixation. The pincer is used for the open reduction of fracture, a person can quickly complete steel wire inner fixing operation, effectively reducing the peeling and the damage of soft tissues in the surrounding of the fracture, simplifying operation, shortening operation time, and effectively improving the therapeutic effect of fracture open reduction steel wire inner fixing.

Description

Steel wire guiding internal fixation pincers

Technical field

This utility model relates to a kind of steel wire guiding internal fixation pincers, is applicable to the bone surgery of fracture open reduction steel wire internal fixation, belongs to the operating theater instruments that orthopaedic trauma uses.

Background technology

At present, the common fixation with steel wire method of fracture open reduction wire internal fixation is to use curved forceps or other clamping devices, steel wire is passed to an other side by a key side from the fracture rear, need both hands or double compounding practice, the location is imprecise when placing fixation with steel wire, change the fixed position difficulty, can't under direct-view, operate when the fracture soft tissue is thicker, also need large tracts of land cleavage fracture place surrounding soft tissue simultaneously so that clamping device passes through, increased the weight of the damage of fracture surrounding soft tissue, prolonged operating time, increased hemorrhage and infection chance.

The utility model content

The drawback that this utility model exists at above-mentioned prior art and a kind of steel wire guiding internal fixation pincers are provided use single all the fracture steel wire internal fixation of can finishing of these pincers to operate, and operation wound is little, and the fixed position accurately and reliably.

The technical scheme of this utility model steel wire guiding internal fixation pincers is as follows:

A kind of steel wire guiding internal fixation pincers, caliper comprises clamp head part, joint portion, grip part, it is characterized in that: the bilateral correspondence is provided with the steel wire guide channel in the clamp head part, pass through to hold steel wire, the opening of guide channel is located at clamp head part side and clamp head part occlusal surface respectively, and the occlusal access portal of bilateral is coincide mutually.

Above-mentioned steel wire guiding internal fixation pincers comprise that upper limb pincers and lower limb clamp two kinds, and caliper is a stainless steel, and upper limb pincers entire length is 170mm, and thickness is 10mm, and wherein clamp head part length is 55mm, and joint portion length is 15mm, and grip part length is 100mm; Lower limb pincers entire length is 190mm, and thickness is 10mm, and wherein clamp head part length is 75mm, and joint portion length is 15mm, and grip part length is 100mm.

The sweep radius upper limb pincers of above-mentioned clamp head part are 25mm, and the lower limb pincers include the steel wire guide channel for 35mm, and wall thickness is 15mm, and guide channel length upper limb pincers are 88mm, and the lower limb pincers are 110mm, and internal diameter is 2mm, and channel direction is consistent with the clamp head part flexibility.

Above-mentioned guide channel one side opening is 30mm in the clamp head part side apart from the terminal upper limb pincers of clamp head part, and the lower limb pincers are 40mm, and the opening part diameter is 3mm; One side opening is in bite, and this place's opening diameter is identical with the passage internal diameter.

Above-mentioned occlusal surface length is 10mm, and is identical with the caliper width, and the occlusal surface width is 5mm, and the guide channel opening is positioned at occlusal surface central authorities, apart from upper limb 1.5mm, apart from lateral margin 4mm; The occlusal surface surface is the strip band, and fringe spacing is 1mm, is higher than occlusal surface 0.5mm.

The beneficial effect of this utility model steel wire is:

This utility model steel wire guiding internal fixation pincers, the bone surgery of open reduction steel wire internal fixation is used to fracture, after the fracture open reduction, be snapped at fracture with the internal fixation pincers, steel wire is entered by the terminal side guide channel mouth of clamp head part, walking around the backbone along guide channel passes from the passage opposite side, unclamp the binding clip bite then, withdraw from steel wire guiding internal fixation pincers and interlock, this moment, steel wire was around a key week and butt up against the binding clip bite, fracture steel wire internal fixation can be finished in hold with a firm grip caliper grip part and rotate caliper.These pincers are used for open reduction of fracture, the single steel wire internal fixation of can finishing is rapidly operated, fixing reaching changes the position accurately and reliably, effectively reduced peeling off and damaging of fracture surrounding soft tissue, simplified operation technique, shorten operating time, reduced operation blood loss and infection risk, thereby improved the therapeutic effect of fracture open reduction wire internal fixation comprehensively.

The specific embodiment

Describe this utility model in detail below in conjunction with drawings and Examples:

Steel wire guiding internal fixation pincers as shown in Figure 1, caliper is to be made of clamp head part 1, joint portion 2 and grip part 3, the bilateral correspondence is provided with the steel wire guide channel in the clamp head part 1, pass through to hold steel wire, the opening of passage is located at clamp head part 1 side and clamp head part 1 occlusal surface 4 respectively, and the access portal of bilateral occlusal surface 4 is coincide mutually.
