Abstract
The purpose of this utility model is to propose a kind of dilator with holes, can be cooperated with needle body, it is minimally invasive it is lower soft tissue is strutted, give away one's position bone, to reduce operation wound and difficulty.The dilator with holes of the utility model includes two calipers for being symmetrical arranged and being connected by shaft, and key is that the front end of described two calipers is equipped with through-hole, and the axial direction of the through-hole is axial parallel with shaft.When during bone surgery, when target bone location is deeper, first needle body (such as saying the common Kirschner wire of bone surgery) can be inserted near targeted bone at the soft tissue of two sides, and the through-hole of two caliper front ends is covered on corresponding needle body, then without in the case where expanding surgical wound, needle body can be driven to strut soft tissue using caliper, targeted bone be exposed, to be operated.
Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of minimally invasive soft group in bone surgery
Knit distraction instrument.
Background technique
In bone surgery, it usually needs give away one's position bone, to reach therapeutic purposes.In minimally invasive situation, due to cutting
Small, deeper for the position targeted bone of mouth, usual difficult exposure need prolonged incison, until the bone that gives away one's position, increases operation
Wound causes operating time to extend, and operating difficulty increases.
Utility model content
The purpose of this utility model is to propose a kind of dilator with holes, can be cooperated with needle body, minimally invasive lower to soft group
It knits and is strutted, give away one's position bone, to reduce operation wound and difficulty.
The dilator with holes of the utility model includes two calipers for being symmetrical arranged and being connected by shaft, and key is
The front end of described two calipers is equipped with through-hole, and the axial direction of the through-hole is axial parallel with shaft.
When during bone surgery, when target bone location is deeper, needle body (such as first can be said that bone surgery is common
Kirschner wire) be inserted into targeted bone nearby at the soft tissue of two sides, and the through-hole of two caliper front ends is covered in corresponding needle body
On, then without in the case where expanding surgical wound, it can drive needle body to strut soft tissue using caliper, expose mesh
Bone is marked, to be operated.
Further, which further includes a tooth plate, in described two calipers, the rear end of caliper and tooth plate
One end is hinged, and tooth plate is equipped with rack gear towards the end face of caliper, and the rear end of another caliper is equipped with the latch that can be caught in rack gear.It is supportting
It opens after device reaches and be satisfied with position, latch is caught in rack gear, so that the aperture of fixed dilator, keeps the distraction angle of dilator
Stablize.
Further, the lateral surface of the caliper is equipped with anti-skid chequer, is held with facilitating.
The utility model has done on traditional dilator and has cleverly changed, and allows to cooperate with needle body, to strut position
Deeper soft tissue is set, the operation of operation is facilitated, there is good practicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the dilator of the utility model.
Attached drawing mark: 1, caliper；2, shaft；3, through-hole；4, tooth plate；5, latch.
Specific embodiment
It is such as involved to specific embodiment of the present utility model by the description to embodiment below against attached drawing
The shape of each component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. make
It is further to be described in detail.
Embodiment 1:
The present embodiment proposes a kind of dilator with holes, can cooperate with needle body, lower supports to soft tissue minimally invasive
It opens, give away one's position bone, to reduce operation wound and difficulty.
As shown in Figure 1, the dilator with holes of the present embodiment includes a tooth plate 4 and is symmetrical arranged and passes through shaft 2
The outside of two calipers 1 of connection, caliper 1 is equipped with anti-skid chequer, and the front end of two calipers 1 is equipped with through-hole 3, the through-hole 3
It is axial axial parallel with shaft 2；In two calipers 1, the rear end of a caliper 1 and one end of tooth plate 4 are hinged, 4 direction of tooth plate
The end face of caliper 1 is equipped with rack gear, and the rear end of another caliper 1 is equipped with the latch 5 that can be caught in rack gear.
When during bone surgery, when target bone location is deeper, needle body (such as first can be said that bone surgery is common
Diameter 3.0mm Kirschner wire) be inserted into targeted bone nearby at the soft tissue of two sides, and by 3 sets of the through-hole of two 1 front ends of caliper
On corresponding needle body, then without in the case where expanding surgical wound, it can drive needle body by soft tissue using caliper 1
It is strutted, exposes targeted bone, then latch 5 is caught in the rack gear of tooth plate 4, so that the aperture of fixed dilator, makes to strut
The distraction angle of device keeps stablizing, to be operated.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specifically design not by
The limitation of aforesaid way, as long as the improvement for the various unsubstantialities that the conception and technical scheme for using the utility model carry out,
Or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
Claims (2)
1. a kind of dilator with holes, including two calipers for being symmetrical arranged and being connected by shaft, it is characterised in that described two
