Abstract
The invention discloses a pull hook for a soft tissue channel. The pull hook comprises a handle and a working end. The included angle between the handle and the working end ranges from 30 degrees to 60 degrees. The working end is of a semi-cylinder shape or cylinder shape and comprises a handle connecting end, a tail end and a side wall with multiple small holes. The pull hook has the advantages that design is reasonable, the included angle between the working end and the handle is an acute angle, efforts are saved, injury to soft tissue is reduced, it is unnecessary to pull the soft tissue with efforts in use, and the space where the pull hook for the channel is placed is an operation space; all operations including titanium nail driving and bone cutting are completed in the working end and isolated from the surrounding soft tissue to protect the soft tissue; the small holes formed in the side wall of the working end of the pull hook for the channel can contain transbuccal trochar instrumentation and also can drain water.
Description
Technical field
The present invention relates to medical apparatus and instruments, more particularly, relate to a kind of drag hook for soft tissue tunnel.
Background technology
Surgery tractor is one of apparatus the most frequently used in art, and it is that patient exposes the visual field large as far as possible in otch little as far as possible, and with raising surgical quality, shorten operating time, reducing operation wound has tight association.Different operative sites needs to use different drag hooks, the relation of oromaxillo-facial region because dissecting, operation technique narrow space, again because of in recent years, Maxillary region endoscope minimally invasive operation increases year by year, some operation needs otch to be positioned at concealment part, arrives operative region through soft tissue tunnel, needs special drag hook for this reason and supports to place endoscope system and operating theater instruments.
Be not exclusively used at present the drag hook in soft tissue tunnel, the shortcoming of other traditional drag hooks: 1. in order to expose working place as far as possible, need be excessive to surrounding soft tissue's tractive, the usually important feature such as the neural and blood vessel of damage surface, causes facial paralysis and the complication such as hemorrhage; 2. not enough to surrounding soft tissue's protection, the soft tissue that drag hook cannot cover is easy to the accidental injury being subject to sharp object and power drill; 3. easily slippage, exposes the nervus vasculairs that should protect, causes patient to accidentally injure, thus misleads hands art; 4. because the volume of drag hook itself, the direction of operating of apparatus is easily stopped, the normal operating of interference operating theater instruments.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of drag hook being exclusively used in soft tissue tunnel.
In order to solve the problem, the invention provides a kind of drag hook for soft tissue tunnel, it is characterized in that, comprise handle and working end, described handle becomes 30-60 to spend angle with working end, described working end is semi-circular cylindrical or cylindrical shape, comprises handle attachment end, end and sidewall, and its sidewall arranges some apertures.
As a preferred version, when described working end is semi-circular cylindrical, the diameter of handle attachment end is slightly larger than the diameter of end.
As a preferred version, the length of described working end sidewall can regulate.
As a preferred version, described handle and working end are in angle of 45 degrees.
As a preferred version, described handle arranges handle hole, during operation technique, finger can be hooked in handle hole place and apply active force.
The invention has the advantages that, 1. reasonable in design, working end and drag hook acutangulate, and reduction is exerted oneself and to soft tissue injury, without the need to tractive soft tissue of exerting oneself during use, namely the space that tunnel drag hook is placed is operative space.2. all operations comprise beat titanium nail, osteotomy etc. all complete in working end, isolate with surrounding soft tissue, play a protective role.3. tunnel drag hook working end sidewall arranges some apertures, the placement of wearing cheek device can be held, also can play the effect of draining.
Accompanying drawing explanation
Fig. 1 is a kind of hook structure schematic diagram for soft tissue tunnel of the present invention.
Label in Fig. 1 is: 1---hands handle; 11---handle hole; 2---working end; 21---aperture; 22---handle attachment end; 23---end; 24---sidewall.
Label in Fig. 2 is: 2 '---cylindric working end.
Detailed description of the invention
Elaborate to the present invention below in conjunction with accompanying drawing, the purposes of embodiment is only to explain the present invention and non-limiting technical scheme.
Embodiment 1.
Refer to Fig. 1, a kind of drag hook for soft tissue tunnel, comprise handle 1 and working end 2, described handle 1 spends angle for 2 one-tenth 30-60 with working end, preferably 45 degree of angles, and working end 2 is in semi-circular cylindrical, comprise handle attachment end 22, end 23 and sidewall 24, its sidewall 24 arranges some apertures 21.
Continue see Fig. 1, working end 2, in semi-circular cylindrical, is thought of as half tunnel space.The diameter of preferred handle attachment end 22 is slightly larger than the diameter of end 23.Sidewall 24 arranges some apertures, can hold the placement of wearing cheek device, also can play the effect of draining.The diameter of handle attachment end 22 slightly larger than the diameter of end 23, easily can insert soft tissue, more convenient drag hook effect during operation like this; Two ends equal diameters does not also affect operation, needs comparatively noticeable effort when just drag hook inserts; The diameter of end also can be reduced into the blunt point of a circle, easier when inserting like this, if but be reduced into the blunt point of a circle, the aperture on sidewall can be reduced, also namely reduce the working place of wearing cheek device.
The length of working end 2 can regulate.Working end can be designed to the two-part that is nested, regulate its length by swivel nut, or the draw-in groove maintenance by being nested, elongate or shorten its length.
Handle 1 is arranged handle hole 11, during operation technique, finger can be hooked in handle hole place and apply active force.
Refer to Fig. 2, as another preferred embodiment, there is cylindric working end 2 ', during the operation of working end, form complete tunnel space.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
