Abstract

The utility model relates to a skull traction bow for a fracture or a dislocation of cervical vertebrae and a serious cervical spondylosis. The utility model comprise a bow frame of the traction bow which is fixed via a connecting shaft, and the left and right sides of the bow frame are symmetric. One end of the bow frame is provided with a regulator. The utility model is characterized in that the other end of the bow frame is provided with a synchronous tube. A skull hook with a screw thread is fixed in the synchronous tube. Positioning, local anesthesia, cutting and drilling are convenient because of the synchronous tube of the utility model, and the synchronous tube and the known skull hook of the traction bow have the same direction and the same angle. When the skull hook with a threaded cusp is pierced in a lamina externa cranii, the engagement is tight, and the hook does not unhook. The utility model has the advantages of simple operation, high speed, high safety and small incision. The utility model eases patients' pain.

Description

The novel skull traction bow of band lock-in tube

This utility model belongs to medical apparatus and instruments, is mainly used in fracture of cervical vertebra or/and the skull traction tool of dislocation and serious cervical spondylosis.

Current, employed skull traction bends as shown in Figure 1 when doing skull traction both at home and abroad, cranium hook 5 (have another name called and grab nail) by shelf 1 and shelf angle demodulator 4 and shelf front end is formed, its shortcoming is a trivial operations, and damage is big, and is time-consuming, the up-bow difficulty, break off relations easily, disadvantages such as patient's fear are stood up in the inconvenience nursing.

The purpose of this utility model provides a kind of novel skull traction easy and simple to handle, reliable, quick, that be difficult for breaking off relations and bends.

Skill scheme of the present utility model is by connecting axle traction bow shelf left-right symmetric to be fixed, on an end of traction bow shelf, actuator is housed, have on the other end and traction bow cranium hook position, direction, the lock-in tube that angle is the same is fixed with threaded cranium hook in the lock-in tube.

In the technique scheme said threaded cranium hook be shaped as a screw that has a groove, be fixed in the lock-in tube with pinning.

Said pinning is fixed in the radially screw of lock-in tube in the technique scheme, is complementary with groove on the threaded cranium hook, withstands on and makes upper and lower location in this groove.

Be fixed with on the fixed axis of said two traction bow shelves in the technique scheme and can load and unload handle flexibly.

This utility model is compared following advantage with prior art: 1. have and known traction bow cranium hook direction, lock-in tube that angle is the same, be convenient to the location, local anaesthesia, otch and boring; 2. on the fixed axis of shelf, be fixed with and load and unload handle flexibly, be convenient to boring, stable operation, smooth; 3. most advanced and sophisticated threaded cranium hook pierces lamina externa cranii, and interlock is tight, does not break off relations; 4. operation is simple and reliable, fast, accurately, safety, otch is little, for patient has alleviated misery.

Fig. 2 is this utility model traction bow lock-in tube structural representation;

Fig. 3 is the threaded cranium hook structure of a this utility model sketch map;

Fig. 4 is the structural representation of this utility model handle;

Fig. 5 is the assembling enlarged drawing of lock-in tube and threaded cranium hook.

The utility model is described in further detail below in conjunction with accompanying drawing.

This utility model is fixed two traction bow shelves, 1 left-right symmetric by axis hole 2 by being connected and fixed axle, have on one rear end of traction bow shelf and traction bow cranium hook 5 directions, lock-in tube 7 that angle is the same, a traction bow shelf 1 has only drawn among Fig. 2, handle 8 can be installed being connected and fixed on the axle during use, so that operation, the other end of traction bow shelf 1 is identical with prior art, and the actuator 4 of scalable two shelf angles is housed; Lock-in tube 7 is a siphunculus, lock-in tube 7 can be split with shelf 1, make a sleeve pipe separately, also can be one, can insert safety drill head and fixing threaded cranium hook 3 in the lock-in tube 7, safety drill head can insert location in the lock-in tube 7, skull is holed, and threaded cranium hook 3 shapes such as same screw are threaded on one end, have medicated cap on the other end, as shown in Figure 3, have groove on the threaded cranium hook 3, threaded cranium hook 3 can be fixed in the lock-in tube 7 with pinning 6, its fixed form is, on the tube wall of lock-in tube 7, radially have a screw through hole, the corresponding cooperation of groove on the fixing pinning 6 in this screw, pinning 6 and threaded cranium hook 3, threaded cranium hook 3 is fixed in the lock-in tube 7 location up and down, as shown in Figure 5.

Operation principle: the skull traction bow lock-in tube 7 impression scalp location that will harmonize fixed, from lock-in tube 7 puncture local anesthesia, to be embossed to the center, the about 10mm of crosscut scalp, strip off scalp periosteum is to lamina externa cranii up and down, lock-in tube 7 is inserted respectively in the two incision, and the tight smooth outside plate of the mouth of pipe maintains static, and takes the circumstances into consideration to select to expose the dark safety drill head of the synchronous mouth of pipe 3～5mm and inserts lock-in tube 7, support skull and pull open brill outward, bore motionless till, the degree of depth withdraws from drill bit just near inner panel, the threaded cranium hook 3 of coupling is imported in the outside plate boring from lock-in tube 7, and tighten, withdraw from handle 8, can carry out skull traction.
