Abstract

The utility model discloses a retention tent nail, which belongs to the field of medical tools and comprises an internal bone nail, wherein the internal thread of the internal bone nail is connected with a clamping nail. The utility model discloses during the use earlier pass the lower extreme of nail in the bone cortex squeezes into the spongy bone, then lay the biomembrane in the bone nail then with centre gripping nail screw in bone in the nail again, can support the biomembrane through mutually supporting of nail in the bone and the centre gripping nail, can carry out spacing fixed to the biomembrane through the centre gripping nail simultaneously, avoid the biomembrane to take place the skew, then the edge of nail to the biomembrane is fixed in utilizing the bone, can let the biomembrane wrap up the bone meal through this kind of mode, make the bone meal can be more stable in the biomembrane, avoid the bone meal in the biomembrane to become in disorder.

Description

Fixed tent nail

Technical Field

The utility model relates to the field of medical tools, in particular to a fixing tent nail.

Background

Guided bone tissue regeneration techniques were first derived from guided tissue regeneration techniques in the field of periodontics. Since the 80 s of the last century, the technology of dental implantation has been widely popularized and applied, and a great number of patients with tooth loss select dental implants for restoration, so that the function and the appearance are better recovered. However, in clinic, a large number of patients have insufficient bone mass in the edentulous area due to various reasons, and cannot directly carry out implantation treatment. At the moment, most students begin to apply a bone regeneration guiding technology to guide the regeneration of bone tissues in the tooth lacking area, a three-dimensional bone space meeting the requirement of implant implantation is formed, and finally implant repair is realized.

Need utilize when carrying out bone tissue regeneration technique retention nail or tent nail to support the biomembrane, then cultivate the bone meal parcel between biomembrane and human tissue, but fixed position nail is difficult to the location when using, and is poor to the fixed effect of biomembrane, and the tent nail can only play the effect of supporting the biomembrane, can't carry on spacingly to the biomembrane. Accordingly, the present invention is directed to a retention tent peg that solves the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a fixing tent nail to solve the problems in the prior art.

In order to achieve the above object, the utility model provides a following technical scheme:

the retention tent nail comprises an intra-bone nail, wherein the intra-bone nail is internally threaded with a retention nail.

As a further proposal, the upper end fixed connection of the bone internal nail is provided with a spacing head, and the spacing head is provided with a polygonal groove.

As the utility model discloses further scheme again, the connecting hole has been seted up to nail inside in the bone, the centre gripping nail is located the connecting hole.

As the utility model discloses the scheme of furthering again, the upper end fixedly connected with connector of clamping nail, the spread groove has been seted up on the connector, the spread groove sets up to "ten" font.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses during the use, earlier pass the bone cortex with the lower extreme of nail in the bone and squeeze into the spongy bone in, then lay the biomembrane in the bone on the nail then with centre gripping nail screw in bone in the nail again, can support the biomembrane through mutually supporting of nail in the bone and the centre gripping nail, can carry out spacing fixed to the biomembrane through the centre gripping nail simultaneously, avoid the biomembrane to take place the skew.

2. The utility model discloses during the use, utilize the intraosseous nail to fix the edge of biomembrane, can let the biomembrane wrap up the bone meal through this kind of mode, make the bone meal can be more stable in the biomembrane, avoid the bone meal in the biomembrane to become in disorder.

Drawings

Fig. 1 is a schematic view showing the structure of the tent retention nail.

Fig. 2 is a disassembled view of the intraosseous nail and the clamping nail of the retention tent nail.

Fig. 3 is a schematic view showing the use of the tent retention nail.

In the figure: 1. an intraosseous nail; 2. a limiting head; 3. connecting holes; 4. a polygonal groove; 5. clamping the nail; 6. a connector; 7. connecting grooves; 8. cancellous bone; 9. cortical bone; 10. a biofilm; 11. bone meal.

Detailed Description

Please refer to fig. 1-3, the embodiment of the utility model provides an in, maintenance tent nail, nail 1 in the bone, the upper end fixed connection of nail 1 in the bone has spacing head 2, polygonal groove 4 has been seted up on the spacing head 2, is convenient for utilize the spanner to install nail 1 in the bone through polygonal groove 4, connecting hole 3 has been seted up to 1 nail inside in the bone, 1 female connection of nail has the clamp nail 5 in the bone, clamp nail 5 is located connecting hole 3, the upper end fixedly connected with connector 6 of clamp nail 5, spread groove 7 has been seted up on connector 6, spread groove 7 sets up to "ten" font, is convenient for utilize the screwdriver to dismantle clamp nail 5 through spread groove 7.

The utility model discloses a theory of operation is:

the utility model discloses during the use earlier in the bone nail 1 the lower extreme pass bone cortex 9 squeeze into in the spongy bone 8 (promptly in the bone nail 1 can not squeeze into spongy bone 8 completely), then lay biomembrane 10 in the bone nail 1 go up then will clamp nail 5 screw in to the bone in nail 1 again, can support biomembrane 10 through mutually supporting of nail 1 in the bone and centre gripping nail 5, can carry out spacing fixed to biomembrane 10 through clamping nail 5 simultaneously, avoid biomembrane 10 to take place the skew, then nail 1 fixes the edge of biomembrane 10 in utilizing the bone, can let biomembrane 10 wrap up bone meal 11 through this kind of mode, make bone meal 11 can be more stable in biomembrane 10, avoid bone meal 11 in the biomembrane 10 to become in disorder.
