Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a fracture reduction and nailing forceps. Background Technique
[0002] As is well known, a fracture refers to the complete or partial rupture of the continuity of bone structure, which is more common in children and the elderly, and also occurs in young and middle-aged people from time to time. Patients often have fractures in one part, and a few have multiple fractures. After timely and appropriate treatment, most patients can recover their original functions, and a few patients may have different degrees of sequelae. Generally, to treat fractures, pliers are needed to restore the bone to its original position, and then bone nails are used for fixation.
[0003] When medical staff use the fracture reduction and nailing forceps to hold the fracture site, since the distance between the clamping head and the handle of the forceps is relatively far, the gravity generated downward by the handle and the forceps body will generate a large pulling force on the clamped part of the clamping head, reducing the stability of the clamping head for clamping the fracture site. To avoid the clamping head from being subjected to a large pulling force, medical staff often need to hold the handle, so the practicability is not very good. Secondly, because the fracture reduction and nailing forceps itself is relatively long and occupies a large space, when medical staff use devices such as electric drills to drill holes in the bone to install bone nails, due to the large length of various tools, the working route is prone to cross the position where the fracture reduction and nailing forceps is located during work. As a result, when drilling or installing bone nails, the tool collides with the fracture reduction and nailing forceps, thus hindering the work of drilling or installing bone nails. Therefore, the practicability is not very good and there is still room for improvement. Content of the Utility Model
[0004] (I) Technical Problems to be Solved
[0005] In view of the deficiencies of the prior art, the utility model provides a fracture reduction and nailing forceps, which has the characteristic of improving practicability.
[0006] (II) Technical Solutions
[0007] To achieve the above object, the utility model provides the following technical solution: a fracture reduction and nailing forceps, including a forceps body, several clamping blocks are arranged on the left part of the forceps body, and shells are respectively clamped thereon. One end of each of the several shells is provided with a clamping plate, and the several clamping plates cooperate to clamp the fracture site. The right parts of the several clamping plates are respectively rotatably connected with connecting rods through rotating shafts, and the several connecting rods penetrate and are connected with a tightening device for fixing the several clamping plates.
[0008] Furthermore, the tightening device includes a telescopic plate, a first threaded hole is arranged in the middle of the telescopic plate, and a first bolt is threadedly connected thereto.
[0009] Further, second threaded holes are provided in the right parts of several of the said shells, and second bolts are threadedly connected thereto. Third threaded holes are provided in the middle parts of several of the said clamping blocks, and they are threadedly connected to the corresponding second bolts.
[0010] Further, one end of each of several of the said clamping plates is provided with a clamping panel, and several anti-slip stripes are provided at one end of each of several of the said clamping panels.
[0011] Preferably, a gap is provided between the lower end face of the telescopic plate and the upper end face of the corresponding clamping plate, and a space is provided between the lower end face of the telescopic plate and the upper end face of the pliers body.
[0012] Preferably, the left end faces of several of the said shells are all arranged in an arc shape, and an anti-corrosion coating is applied to the outsides of the first bolt and several second bolts.
[0013] (III) Beneficial effects
[0014] Compared with the prior art, the present utility model provides a fracture reduction and nail driving pliers, which has the following beneficial effects:
[0015] For this fracture reduction and nail driving pliers, through the clamping setting of the clamping block on one side of the pliers body and the shell on one side of the clamping plate, it is convenient for the two to be disassembled and installed. After the clamping plate is clamped on the fracture site by operating the pliers body, by tightening the first bolt to fix the length of the telescopic plate, the clamping plate can be fixed to clamp the fracture site. At this time, the second bolt can be unscrewed, and the pliers body and the clamping block can be disassembled from the shell, reducing the overall length of the fracture reduction and nail driving pliers, thereby avoiding the situation where other tools collide with the fracture reduction and nail driving pliers when drilling or installing bone nails. Secondly, since the pliers body is disassembled from the clamping plate, the influence of the gravity of the pliers body itself on the clamping plate is avoided, reducing the downward pulling force on the clamping panel to a certain extent, and thus improving a certain stability, and therefore improving a certain practicality.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-4 , a fracture reduction nail driving forceps of the present invention includes a plier body 1. Several clamping blocks 2 are arranged on the left part of the plier body 1, and are all clamped with a housing 3. One end of several housings 3 is provided with a clamping plate 4. Several clamping plates cooperate to clamp the fracture site. The right parts of several clamping plates 4 are all rotatably connected with a connecting rod 5 through a rotating shaft. Several connecting rods 5 penetrate and are connected with a tightening device for fixing several clamping plates 4.
[0023] The tightening device includes a telescopic plate 6. A first threaded hole is arranged in the middle of the telescopic plate 6 and is threadedly connected with a first bolt 7. By loosening the first bolt 7, the length of the telescopic plate 6 extending out can be adjusted, so as to facilitate the several clamping plates 4 to be at different unfolding angles. When clamping the fracture site, tighten the first bolt 7 to firmly fix the telescopic plate 6 at this length, so that the several clamping plates 4 firmly clamp the fracture site.
[0024] Second threaded holes 8 are arranged on the right parts of several housings 3 and are all threadedly connected with second bolts 9. Third threaded holes 10 are arranged in the middle of several clamping blocks 2 and are all threadedly connected with the corresponding second bolts 9. By screwing the second bolts 9 into the second threaded holes 8 of the housings 3 and the third threaded holes 10 of the corresponding clamping blocks 2, the clamping blocks 2 can be firmly fixed on the housings 3, thereby improving the stability between the two.
[0025] One end of several clamping plates 4 is provided with a clamping panel 11. One end of several clamping panels 11 is provided with several anti-slip stripes 12 for increasing the friction between the clamping panel 11 and the fracture site.
[0026] A gap is arranged between the lower end face of the telescopic plate 6 and the upper end face of the corresponding clamping plate 4 to prevent the several clamping plates 4 from rubbing against the telescopic plate 6 when rotating. A space is arranged between the lower end face of the telescopic plate 6 and the upper end face of the plier body 1 to facilitate the installation of the clamping block 2 on one side of the plier body 1 in the housing 3 without rubbing against the telescopic plate 6.
[0027] The left end faces of several shells 3 are all arranged in an arc shape, which can reduce the extrusion force generated on the flesh tissue when the shell 3 enters the flesh tissue of the patient. An anti-corrosion coating is applied to the outside of the first bolt 7 and several second bolts 9, which can improve the anti-corrosion effect.
[0028] In summary, when using this fracture reduction nail forceps, the medical staff inserts the clamping block 2 on one side of the forceps body 1 into several shells 3, and clamps the clamping plate 4 on the forceps body 1. Then, the second bolt 9 can be screwed into the second threaded hole 8 of the shell 3 and the third threaded hole 10 of the corresponding clamping block 2 to fix the clamping block 2 and the shell 3 together. Then, the medical staff loosens the first bolt 7 to make the telescopic plate 6 in a telescopic state. At this time, hold the handle of the forceps body 1, and then drive the clamping plate 4 to move to the fracture site of the patient, contract the opening angle of the forceps body 1, drive the clamping plate 4 to contract the opening angle, and at the same time contract the telescopic plate 6. When the anti-slip stripes 12 on the clamping panel 11 at one end of several clamping plates 4 clamp on the fracture site, the first bolt 7 can be tightened to firmly fix the telescopic plate 6, so as to firmly fix several clamping plates 4 in this clamped state. Then, the second bolt 9 is unscrewed, and the clamping block 2 is pulled out of the shell 3, and the forceps body 1 can be disassembled from the clamping plate 4, and then the operation can be carried out.
[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
