A sliding block provided with the bone flap opening knife is clamped on the sliding pipe and is provided with a fastening screw. A knife head at the front end of the bone flap opening knife on the sliding block and a horizontal direction form an angle with 60 DEG. A knife edge and the horizontal direction form an angle with 45 DEG-55 DEG. The front end of the sliding pipe is provided with a pressing handle for compacting. The utility model has the advantages of scientific and reasonable structural design, and simple and convenient operation in use. The whole operation can be completed in a short time. The utility model has better functions for the accomplishment and the effect of the whole operation.

Description

Craniocerebral operations bone lobe opener

This utility model belongs to the neurosurgery apparatus, mainly proposes a kind of craniocerebral operations bone lobe opener.

In the neurosurgery,, and adopt some other operating theater instruments to replace at present,, and need to finish smoothly by three kinds of apparatuses of operation more than two people as bone sled, periosteum stripping, rongeur because be not specifically designed to the apparatus of opening the bone lobe; The method of opening the bone lobe at present is, in four holes of cranial drill, cut three and keep one side with scroll saw, because of there being tissues such as muscle to connect on this one side, monoblock is not dropped, periosteum stripping is placed in pressurization on this one side, places bone sled and rongeur in addition near 2 under the bone lobe, firmly laterally the bone lobe is raised.Traditional method directly influences operative speed, and the time of opening the bone lobe is longer, and it is more that patient is lost blood, and influence the healing of postoperative, and problems such as bone window edge is irregular very easily occur.

The purpose of this utility model is to propose a kind of cranium from operation bone lobe opener, make its have easy to operate, the opening time fast, good effectiveness.

This utility model is finished the technical scheme that its invention task taked: it includes the bone lobe and opens cutter, and slide block and slip pipe are adjusted in the position; Have the bone lobe and open the slide block of cutter and be clamped on the slip pipe and be provided with trip bolt, the bone lobe on the slide block is opened its front end cutter head of cutter and horizontal direction is 60 ° of angles, and blade and horizontal direction are 45 ° of-55 ° of angles, and the slip pipe front end is the pressure handle that compresses usefulness.

This utility model scientific structure design is reasonable, in the use operation comparatively easy, whole surgery is finished at short notice, finishing of whole surgery and effect are all had better action.

Embodiment:

Accompanying drawing 1 is this utility model structural representation.

Sketch map when accompanying drawing 2 is operated for this utility model.

The embodiment that provides with reference to accompanying drawing is further specified this utility model structure:

As shown in drawings: it includes, and the bone lobe is opened cutter 5, the position adjusts slide block 4 and slip pipe 1, unlatching cutter 5 are arranged on the slide block 4, and can be also fixing in the position of slide block 4 by adjusting hold-down screw 3 adjustment unlatching cuttves 5, cutter head and horizontal direction that the bone lobe is opened cutter 5 front ends are 60 ° of angles, and blade and horizontal direction are 45 ° of-55 ° of angles.Slide block 4 be clamped on the slip pipe 1 and available trip bolt 2 fastening, slip pipe 1 front end has pressure handle 6, pressure handle 6 has certain radian.

As shown in Figure 2: cut three of BC, CD, DA at 4 at sphenotresia A, B, C, D and with scroll saw, keep the AB face, because of there being tissues such as muscle to connect on the AB face, monoblock is not dropped, the cutter head of the bone lobe being opened cutter 5 places under the bone lobe of CD line, adjusts slip pipe 1 its front end pressure handle 6 is placed on the AB face, and fixedly trip bolt 2, outwards exert oneself with the rear end of holding slip pipe 1 on the other hand, the bone lobe is raised.

Claims

1, a kind of craniocerebral operations bone lobe opener, feature is: it includes, and the bone lobe is opened cutter (5), slide block (4) and slip pipe (1) are adjusted in the position; The slide block (4) that has bone lobe unlatching cutter (5) is clamped in slip pipe (1) and goes up and be provided with trip bolt (2), bone lobe on the slide block is opened its front end cutter head of cutter and horizontal direction is 60 ° of angles, blade and horizontal direction are 45 ° of-55 ° of angles, and slip pipe (1) front end is the pressure handle (6) that compresses usefulness.
