Description
Technical Field
The utility model belongs to medical machinery, in particular to an auxiliary traction device for the surgical treatment of condyloid fracture.
Background
The condyloid fracture is a common fracture of the mandible, and is usually caused indirectly by hitting the chin or the body or the lifting part of the opposite mandible by external force, and the fracture is divided into three types according to the different parts: 1. intravesicular fracture: the condylar fracture is generated above the attachment of the lateral pterygoid muscle, and the fracture or the injury is generated only on the articular surface, so that the condylar fracture is not influenced by the traction of the lateral pterygoid muscle and does not generate the displacement (high fracture); 2. condyloid cervical fracture, fracture located outside joint capsule and below the attachment of lateral pterygoid muscle (median fracture); 3. condyloid-base fracture-fracture at the level of the sigmoid notch (low position fracture). In terms of treatment, the high condyloid-process fracture cannot be displaced, so that disorder of biting (occlusal) relation and mouth opening limitation cannot be caused, continuous observation can be carried out, photographing observation can be carried out regularly, and if progressive mouth opening limitation occurs, the fractured end of the condyloid-process fracture needs to be removed by operation; for middle-position and high-position fractures, the broken end of the condyloid process of the fracture can be displaced inwards due to the traction of extrapteromalies, the broken end of the mandible can be displaced upwards due to the traction of the elevator group of the intraductal muscles, the masseter and the temporalis muscles, the vertical distance of the elevator can be reduced, so that the posterior teeth are contacted early and the anterior teeth are opened (occlusal), generally, the conservative treatment can be carried out, namely the posterior teeth are lifted up and the jaw is drawn in parallel, if the bite (occlusal) relationship is still disordered and obvious after one week of drawing, the operative removal or the incisional reduction and strong internal fixation of the broken end of the fracture can be carried out according to the fracture condition. However, in the course of operation treatment, it is found that the condyloid process cannot be directly viewed due to the fact that the lateral pterygoid muscle draws the condyloid process inwards, and the fracture line cannot be naturally exposed after incision due to the fact that the maxillary muscle draws the mandible upwards, and the solution is that the mandible is drawn downwards to completely expose the fracture line and the condyloid process. However, the above operation is prone to the situation that the surgical instrument slips off from the ligature wire and the arm cannot maintain the pulling strength after long-time arm strain due to the awkward pulling posture, which causes the prolongation of the operation time and the working state of the operator, and affects the operation effect.
The utility model has the following contents:
utility model purpose: in order to more conveniently draw the lower jaw body in the operation so as to completely expose the fractured condyloid process, shorten the operation time and maintain the stability of the operation, the application provides an auxiliary drawing device for the operation treatment of the condyloid process fracture.
The technical scheme is as follows: the application a supplementary tractive device for condyloid process fracture surgery treatment, a serial communication port, including the handle, titanium nail fixing device is connected through the connecting rod to handle one end, wherein, the connecting rod is 120 with the handle contained angle, titanium nail fixing device is perpendicular with the handle extension line.
When the included angle between the titanium nail fixing device and the handle is 90 degrees, the mandible is most favorably pulled downwards, and if the included angle of the handle is larger than or smaller than 90 degrees, the mandible is moved inwards or outwards during pulling. Because the traction is needed for a long time in the operation, the angle between the handle and the connecting rod is 120 degrees, so that soft and hard tissues in a non-operation area on the surface of the mandible can be avoided, and the compression to the mandible in the operation is avoided.
Furthermore, the titanium nail fixing device is a titanium nail insertion hole which is used for inserting the titanium nail into the mandible through the titanium nail insertion hole, and then the condyloid process traction device and the mandible form a whole so that the mandible can move along with the titanium nail traction device when force is applied to the handle. Generally, the titanium nail insertion hole is one. According to the practical use condition, the titanium nail placing hole is a stainless steel circular ring, generally, the inner diameter ranges are 2.0mm, 2.1mm and 2.2mm, and the corresponding outer diameters are 3.5mm, 3.6mm and 3.7mm respectively.
In order to ensure the stability of traction in the operation, the auxiliary traction device for the operation treatment of the condyloid fracture is arranged into a fixed connection structure, preferably an integrally formed structure. The design can also avoid the slipping phenomenon of the needle holder and the ligature wire.
The size, shape and the like of the device can be adjusted according to actual conditions, and generally, the handle is in a stainless steel cylinder shape, is 10-15cm long and is 3cm in diameter. The connecting rod is a cuboid, the width of the connecting rod is 1.5cm, and the length range of the connecting rod is 5-10 cm.
Furthermore, in order to facilitate operation, an anti-slip silica gel sleeve is arranged outside the handle.
The working principle is as follows: the auxiliary traction device is used for treating the condyloid fracture operation, an incision is designed in front of an otoscope, skin, subcutaneous tissues and fascia are incised, the posterior boundary of the superficial lobe of the parotid gland is separated obtusely, the zygomatic branch and the temporal branch of facial nerve are protected, a joint capsule is exposed, the joint capsule is incised, a masseter is stripped from the surface of a ascending branch of a mandible downwards, the surface of the ascending branch of the mandible is exposed, a titanium nail fixing device at the working end of the device is placed on the bone surface and is punched by a drill to place a titanium nail, a handle is held by a hand to drag downwards, a fracture line and a condyloid-shaped fracture end are exposed through linkage of a connecting rod, and then internal fixation of fracture incision reduction or extraction of the condyloid-shaped fracture end are determined according to the position of the fracture line and the size and integrity of the condyloid-shaped fracture end.
Has the advantages that: compared with the prior art, the device has a simple and practical structure, and can better expose the broken ends of the fracture line and the condyloid-process fracture by more effectively pulling the mandible to ascend and descend; and after the device is used, the field of vision of the operation can be kept in a long-time stable state in the operation treatment process of the fracture of the condyle of the mandible, so that an operator can conveniently apply force and control the direction for a long time, the operation time can be shortened, the operation effect can be ensured, the manufacturing cost is low, the using method is simple, the study and the grasp are easy, and the rapid popularization and the use can be realized.
