Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of soft tissue expander.
Background technology
Cervical spondylotic myelopathy（Cervical spinal cord is oppressed after disc herniation）It is common disease, long-standing problem patient.At present
Treatment method, mostly using open surgery, i.e. anterior approach discectomy decompression and fusion, its operation wound is big, Huan Zhekang
The multiple time is long, and medical expense is high.With the progress of minimal invasive techniques, backbone scope inferoanterior approach operative treatment ridge is occurred in that
Marrow myelopathy, it is advantageous that：Operation wound is small, local anaesthesia menisectomy, and rehabilitation of patients after surgical treatment is fast, and medical expense is relatively low.The hand
Art need throat side skin cut an about 4mm otch, Needle localization to target area, then insert successively soft tissue expander,
Worked sleeve and backbone scope, and Lumbar intervertebral disc protrusion is extractd under direct-view, makes the spinal decompression of compression.
But it is existing puncture and put pipe process it is blind regard it is lower carry out, it is impossible to accurately adjust expander degrees of expansion, nothing
Method determines whether operating position has oesophagus to slip into, easy damaged oesophagus, once causing damage to oesophagus, will trigger esophageal fistula, causes
Infection, or even threat to life.It is therefore desirable to design an operation tool to improve the technology, to reduce the incidence of esophageal fistula,
And realize that visualization is precisely punctured.

Preferably, the first screw-casing and the second screw-casing are respectively arranged with the first nut and second adjacent to one end of connector
Nut.
Preferably, soft-tissue expansion piece semicircular in shape, its one end away from caliper is taper, and cone angle is in circular arc.
Preferably, the handle portion of caliper is curved.
Preferably, the connected mode between caliper is to be hinged.
Beneficial effects of the present invention are：
1st, when using the present apparatus, by rotary connector, screw rod is can be while be threaded in or out the first screw-casing and the second spiral shell
Rotation set, to realize closure or the separation of caliper flat end, reaches adjustment soft-tissue expansion piece closure or the purpose of separation.
2nd, to be threadedly coupled between screw rod and the first screw-casing and the second screw-casing, closing or expanding soft-tissue expansion piece
During, connector for each revolution, soft-tissue expansion piece is expanded or closes up 2 pitch, thus reaches soft group of fine adjustment
Knit expanding plate and expand degree, accurately to control the tear(ing) strength of wound, solve the unstability that existing hand-held devices are brought.
3rd, wound, rotary connector, you can expand soft tissue are inserted by the soft-tissue expansion piece for closing the present apparatus
Piece expansion is opened, and soft tissue is successively separated until field of operation, is easy to later observation scope by incision by soft-tissue expansion piece
Entrance, field of operation is observed, follow-up operation technique is carried out to avoid oesophagus, tracheae etc., reduces generation esophageal fistula
Probability.
4th, connector surface is provided with some tooth form bars, it is possible to increase frictional force during rotation, is easy to operate device.
5th, the one end of soft-tissue expansion piece away from caliper is provided with circular arc cone angle, in augmenting soft tissue expanding plate to soft group
While knitting cutting force, it can also effectively reduce and damage is brought to soft tissue.

Embodiment
The embodiment to the present invention is described below, in order to which those skilled in the art understand this hair
It is bright, it should be apparent that the invention is not restricted to the scope of embodiment, for those skilled in the art,
As long as various change is in the spirit and scope of the present invention that appended claim is limited and is determined, these changes are aobvious and easy
See, all are using the innovation and creation of present inventive concept in the row of protection.
It is shown as shown in Figure 1, Figure 3 and Figure 4, the soft tissue expander, including two calipers 1 being hinged, caliper 1 includes flat
Straight portion and handle portion, are fixed with the soft-tissue expansion piece 3 of semicircular in shape, the semicircle of two soft-tissue expansion piece 3 at flat part end respectively
The side of shape is relative, and the one end of soft-tissue expansion piece 3 away from caliper 1 is taper, and cone angle is in circular arc, in augmenting tissue expansion
While piece is to Soft tissue cutting power, the damage caused during the insertion wound of soft-tissue expansion piece 3 to soft tissue can be also effectively reduced
Wound.
As shown in figure 1, the handle portion of caliper 1 is curved, and it is provided between the handle portion of two arcs adjusting rod 4,
The closure each other of soft-tissue expansion piece 3 and separation are controlled by adjusting bar 4.
As shown in Fig. 2 adjusting rod 4 includes the first screw-casing 5 and the second spiral being individually fixed between the handle portion of caliper 1
Set 6, and the screw rod 7 being respectively embedded therein, the structure of two screw rods 7 is identical, and the screw-casing 5 of screw rod 7 and first and the second screw-casing 6
It is connected through a screw thread, is provided with left-handed or dextrorotation external screw thread, the first screw-casing 5 and is provided with and the outer spiral shell of screw rod 7 on screw rod 7
Levogyrate inner thread or dextrorotation internal thread that line matches；Be provided with second screw-casing 6 with the external screw thread of screw rod 7 match it is left-handed
Internal thread or dextrorotation internal thread.
If screw rod 7 is sinistral external thread, then be provided with levogyrate inner thread in the first screw-casing 5, and due to the first spiral shell
The screw-casing 6 of rotation set 5 and second is oppositely arranged, then the screw rod 7 in embedded second screw-casing 6 is dextrorotation external screw thread, the second spiral shell
Internal thread in rotation set 6 also need to be set on dextrorotation internal thread, and screw rod 7 externally threaded length respectively with the first screw-casing 5 and
The internal thread length that second screw-casing 6 is set is consistent.
As shown in Fig. 2 two screw rods 7 are individually fixed in the two ends of connector 2, connector 2 is rounded, and its surface is uniformly set
Some tooth form bars are equipped with, to increase friction, by rotary connector 2, screw rod 7 can screw out or screw in simultaneously the first screw-casing
With the second screw-casing, to realize closure or the separation of caliper flat end, the mesh of adjustment soft-tissue expansion piece closure or separation is reached
's.
Meanwhile, to be threadedly coupled between screw rod and the first screw-casing and the second screw-casing, expand closing or expanding soft tissue
During piece, connector for each revolution, soft-tissue expansion piece is expanded or closes up 2 pitch, thus reaches fine adjustment
Soft-tissue expansion piece expands degree, accurately to control the tear(ing) strength of wound, and solve that existing hand-held devices bring is unstable
Property.
As shown in Fig. 2 the first screw-casing 5 and the second screw-casing 6 are respectively arranged with the first nut adjacent to one end of connector 2
