Description

Bone way spacer

Technical Field

The utility model relates to a technical field of the passageway is seted up in bone surgery, in particular to bone way spacer.

Background

In an orthopedic surgery, a bone drill is often used for drilling a bone passage on a bone, and then a suture or other surgical instruments are introduced into the bone passage, however, the diameter of the bone passage is small (generally about 3 mm), the bone passage is often drilled through and filled with a large amount of blood and soft tissues in a human body in the actual surgery process, so that the specific position of the bone passage is difficult to reposition under an arthroscope, and as a result, the surgery time is greatly prolonged, and the surgery risk is increased.

At present, a related positioning tool is lacked, and doctors often choose to enlarge the diameter of a bone passage in order to position the bone passage and introduce a suture in an operation, so that more bone mass is lost, and the risk of iatrogenic fracture is increased. The existing bone path positioning and measuring tools are lacked, the specific position of the bone path is difficult to find under an arthroscope, and due to the fact that the diameter of the bone path is small, the bone path is often required to be enlarged to smoothly introduce a suture, so that more bone mass is lost, and the risk of iatrogenic fracture is increased.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists among the prior art, the utility model aims at providing a bone way spacer, after going into the bone way soon, help the doctor establish stable clear apparatus passageway, from taking measurement function, can measure the degree of depth of bone way. In order to realize the above objects and other advantages in accordance with the present invention, there is provided a bone way spacer, comprising:

the device comprises a bone path occupying rod and a plug embedded with the bone path occupying rod;

the bone path occupying rod is a hollow rod, and scales are marked on the rod body.

Preferably, the bone way spacer comprises a first insertion section, a second thread section integrally connected with the first insertion section, and a scale section integrally connected with the second thread section.

Preferably, one end of the first insertion section, which is far away from the second thread section, is provided with a taper end, and the taper end is used for the bone passage occupying rod and is convenient for being directly installed and inserted into the bone passage.

Preferably, the second thread section is provided with threads, and the threads are used for screwing the bone path occupying rod into the bone path and fixing the bone path occupying rod.

Preferably, the integral type is connected with the rotation piece on the scale section, it is hexagon nut to rotate the piece, a through-hole has been seted up at rotation piece center, the through-hole is corresponding with bone way occupy-place pole hole.

Preferably, the plug is a silica gel plug, the plug comprises an insertion section and a pressing section fixedly connected with the insertion section, and the insertion section is matched with the through hole of the rotating member.

Compared with the prior art, the utility model, its beneficial effect is:

(1) after the product is screwed into the bone channel, the device helps a doctor to establish a stable and clear instrument channel, is convenient for introducing a suture, and avoids repeatedly finding the bone channel through skin.

(2) The product has a measuring function, and the depth of the bone canal can be measured.

(3) Can provide bone way spacer of multiple specification to different operation demands.

Drawings

Fig. 1 is a schematic diagram of a three-dimensional explosion structure of a bone path spacer according to the present invention.

In the figure: 10. a bone tract occupying rod; 20. a plug; 30. a rotating member; 11. a first insertion section; 12. a second thread segment; 13. and (5) a scale section.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a bone way spacer comprising: the bone path occupying rod 10 and the plug 20 embedded with the bone path occupying rod 1 are used for plugging a channel at the tail end of the bone path occupying device 10 when surgical instruments are replaced, so that blood or normal saline in a bone path is prevented from splashing out, and the bone path occupying rod 10 is made of metal pieces; the bone path occupying rod 10 is a hollow rod, scales are marked on the rod body, and when the bone path occupying rod 10 is inserted into a bone path, a doctor can conveniently know the depth of the bone path through the scales on the bone path occupying rod 10.

Furthermore, the bone tract occupation rod 10 comprises a first insertion section 11, a second thread section 12 integrally connected with the first insertion section 11 and a scale section 13 integrally connected with the second thread section 12, a taper end is arranged at one end, away from the second thread section 12, of the first insertion section 11, the taper end is used for the bone tract occupation rod 10 to be convenient for direct installation and insertion into the bone tract, a thread is arranged on the second thread section 12, and the thread is used for screwing the bone tract occupation rod 10 into the bone tract and fixing the bone tract occupation rod.

Further, the integral type is connected with rotation piece 30 on scale section 13, rotation piece 30 is hexagon nut, a through-hole has been seted up at rotation piece 30 center, the through-hole is corresponding with bone way position-occupying pole 10 hole.

Further, the plug 20 is a silica gel plug, the plug 20 includes an insertion section and a pressing section fixedly connected to the insertion section, and the insertion section is matched with the through hole of the rotating member 30.

The working principle is as follows: after the bone canal is established, the first insertion section 11 is inserted into the bone canal, the rotating piece 30 is rotated through the hexagonal wrench, the bone canal occupying rod 10 can be further screwed into the bone canal through the second thread section 12 until the bone canal occupying rod 10 is installed to the bottom, the depth of the bone canal can be known through the scale section 13, after installation, a suture can be introduced into the bone canal from the tail end of the bone canal occupying rod 10, when a surgical instrument is replaced, the plug 20 is inserted into the rotating piece 30, and blood or physiological saline in the bone canal is placed to be splashed out.
