Abstract

The utility model discloses a pair of fixing pliers for fracture, which is composed of pliers heads (1) and pliers tail handles (2), wherein the pliers tips of the pliers heads (1) are in a triangular pyramid shape; the pliers tail handles (2) are provided with fixing grooves; one end of a fixing screw rod (3) is embedded in a left groove of the pliers tail handles, and the other end of the fixing screw rod (3) is fastened by nuts through a right groove which is in parallel with the screw rod. The utility model has the advantages of reasonable structure, flexible and convenient operation, firm fixation, no loosing phenomena and enhanced operation quality, and can be widely used for the treatment of the long oblique fracture of a tibia, the fracture of a spiral bone, inner and outer ankles and three ankles.

Description

The fracture fixation pincers

This utility model belongs to medical instruments field, and what relate generally to is a kind of fracture fixation pincers.

At present, medical department mainly contains following two kinds at the Therapeutic Method that fracture patient is taked; The first, the open reduction internal fixation: can adopt steel plate, screw internal fixation to shin Os Sus domestica fracture, medial and lateral malleolus then adopts screw or Kirschner wire to fix.The second, the solid external fixation of percutaneous clamp: use " Fu Shi pincers " clamp fixedly long Dou shape of tibiofibula, spiral fracture and medial and lateral malleolus fracture, dislocation of ankle joint.The open reduction internal fixation has and resets accurately, fixed advantage, but because it needs skin incision, so damage is big, infect easily, and need do for the second time and perform the operation, and also can leave over cicatrix.Use Fu Shi pincers percutaneous clamp treatment fracture, it is a kind of comparatively ideal method, its have the damage little, need not operate on, the characteristic of simple of performing the operation, but the Fu Shi pincers are to lean on handle (movable) reinforcing of afterbody to make the pincers point snap in cortical bone and play fixation, because of handle longer, make troubles to the operator, when taking off or install, clamp is slided; The fastening of Fu Shi pincers is the tabletting of oppressing trough of belt by nut, and the sliding tray that makes it and clamp compresses and prevents that pincers are loosening, and not consistent with the direction of sliding tray because of tabletting, tabletting can rotate thereupon together when swivel nut.Therefore, after nut screws, can not stop pincers loosening effectively, the pincers point is loosening because of being subjected to the tension force effect that it is opened, and has had a strong impact on the operation quality; The tong arm part of Fu Shi pincers is curved, and the both sides tong arm is formed a circle, in actual applications, and when running into skin and flesh and organize abundanter patient, in the operation and after the operation, tong arm can be oppressed skin, thereby causes cutaneous necrosis, wound is difficult to healing, even long-term the infection, forms osteomyelitis.Because the pincers point of Fu Shi pincers is a cone shape, when the card sclerotin, be difficult in the progress sclerotin.

The purpose of this utility model promptly produces thus, proposes a kind of flexible and convenient operation, and the pincers point snaps in the sclerotin easily, the fracture fixation pincers of fixing back non-loosening phenomenon.These fracture fixation pincers can be applicable to the treatment of the long Dou shape of tibia fracture, spiral fracture, medial and lateral malleolus and trimalleolar fracture.

For achieving the above object, this utility model is achieved through the following technical solutions; Clamp head part is circular arc, and the pincers tip is a rib vertebra shape; With binding clip be that two pincers of integrally-built pincers afterbody all have holddown groove on the handles, an end of standing screw is embedded in the right holddown groove of pincers handle tail mutually, its other end is fastening with nut by right holddown groove.

This utility model reasonable in design, because having omitted, it is used for afterburning removable handle portion, so its flexible and convenient operation, clamp strength is big, because of its fastening employing is fixed with screw rod, nut at handle afterbody fluting, so it is fixed, the non-loosening phenomenon, thus make the pincers point be difficult for sliding, improved the operation quality greatly, and its pincers point is a prismatic, not very easily sticked in the sclerotin by the influence of any skin and flesh tissue.The utlity model has and do not oppress skin, easy, the wrapping back external fixation advantage easily of performing the operation of sterilization, overcome the defective that existing fixation clamps easily causes skin infection, wound to be difficult to heal.

This utility model has following accompanying drawing:

Accompanying drawing 1 is this utility model structural representation.

Accompanying drawing 2 is the structural representation of this utility model handle portion.

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

As shown in the figure: this utility model is made of binding clip 1, pincers tail handle 2, standing screw 3 and nut 4, binding clip 1 is an overall structure with pincers tail handle 2, and binding clip 1 is a circular arc, and nearly tip arc angle is dwindled gradually, the pincers point is a rhizoma sparganic vertebra shape, and its effect is to be convenient to snap in the sclerotin.All have holddown groove on the pincers tail handle 2, an end of standing screw 3 is embedded in the one handle groove (left groove) mutually, can adopt the embedding of pin phasing, and its other end is fixed with nut by the fluting (right groove) on same horizontal another handle with it.Nut adopts six-sided nut, this utility model in use, earlier side pincers point is thrust skin by the entry point of making certainly, and be fixed on the cortical bone surface, and then opposite side pincers point is thrust from another skin entry point of choosing certainly, be fixed on bony surface, make the pincers point be fixed on the both sides of bone, with holding the clencher arm, avoid clamping point and slide then, rock the pincers tail, utilize the rhizoma sparganic vertebra shape of pincers point, make pincers pointed drill people sclerotin, then screw rod tail is screwed in the holddown groove of right side pincers tail swivel nut, in swivel nut, rock the pincers tail, make the more fastening sclerotin of pincers point, also available in case of necessity wrench turn nut increases clamp strength.
