Description

Technical Field

[0001] The utility model relates to the technical field of draw hooks, in particular to a self-cleaning transparent draw hook. Background Art

[0002] The breast and thyroid retractors currently used in clinical practice are made of metal and have only a hook-shaped structure and a handle, which only have the function of pulling open the incision skin to expose the surgical field of view. With the advancement of technology, the use of electric knives has gradually increased. The smoke and bleeding generated by the electric knives during the operation will still blur the surgical field of view, and intermittent small-scale flushing is required during the operation to check for bleeding points.

[0003] Traditional thyroid and breast retractors do not have the function of absorbing smoke generated by electric knives, sucking liquids and flushing. In addition, the metal material will block part of the field of vision and may block some bleeding points, causing inconvenience to medical staff in operation. Utility Model Content

[0004] The utility model aims to provide a self-cleaning transparent draw hook to solve the existing technical problems.

[0005] In order to solve the above technical problems, the utility model specifically provides the following technical solutions: a self-cleaning transparent retractor, comprising a hook body, which is in a transparent hook shape, wherein the inner cavity of the body is provided with a first flushing channel and a first suction pipe in parallel, and both ends of the first flushing channel and the first suction pipe have openings at both ends of the hook body;

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-2 As shown, a self-cleaning transparent retractor comprises:

[0024] The hook body 1 is in a transparent hook shape, and the inner cavity of the hook body 1 is provided with a first flushing channel 3 and a first suction pipe 4 in parallel, and both ends of the first flushing channel 3 and the first suction pipe 4 are opened at both ends of the hook body 1;

[0025] The handle 2 is in the shape of a transparent handle, and the inner cavity of the handle 2 is provided with a second flushing channel 6 and a second suction pipe 5. The first flushing channel 3 is connected with the second flushing channel 6 to form a liquid flow channel for liquid flow, and the first suction pipe 4 is connected with the second suction pipe 5 to form a mixing flow channel for blood or gas flow.

[0026] The retractor has a dual-channel design, which can not only realize the flushing function, but also the cleaning of smoke and blood, effectively removing obstacles that block the medical staff's field of vision. At the same time, the transparent retractor can better expose the surgical field of vision, making it easier for medical staff to operate.

[0027] Specifically, the hook body 1 and the handle 2 are both made of acrylic plate material, and the acrylic plate material is transparent, that is, the hook body 1 will not interfere with the operator's field of vision when in use, and the hook body 1 and the handle 2 can be fixedly connected or detachably connected.

[0028] Since the flow of the fluid in the liquid flow channel and the mixing flow channel requires external driving force, an external driving device must be provided to drive them.

[0029] Specifically, Figure 2 As shown, a water pump 7 is provided in the inner cavity of the second flushing channel 6 to control the flow of liquid in the second flushing channel 6.

[0030] The end of the handle 2 away from the hook body 1 is connected to a negative pressure device 8 and a liquid storage device 9 through pipes. The negative pressure device 8 is connected to the second suction pipe 5 to drain the smoke or blood in the first suction pipe 4. The liquid storage device 9 is connected to the second flushing channel 6 to transport the flushing liquid to the first flushing channel 3 under the action of the water pump 7.

[0031] The pipes connecting the negative pressure device 8, the liquid storage device 9 and the handle 2 are all connected in a detachable manner to facilitate the separate storage of the retractor.

[0032] Since the hook body 1 is a transparent hook, it will not block the transmission of light under the illumination of light when in use. Also, since the hook is the closest to the patient, the installation position of the illumination light source can take into account the hook itself, so as to make the operator's field of vision clearer.

[0033] Specifically, Figure 2 As shown, a light source 10 is provided at one end of the handle 2 close to the hook body 1, so that the surgical site of the patient is completely exposed to the light source 10, wherein the light source can be a lamp. As the operation progresses, the surgeon does not need to constantly change the position of the shadowless lamp to seek the best light source to illuminate the hidden cavity.

[0034] Furthermore, if Figure 1 As shown, a control switch 11 is provided on the handle 2 , and the control switch 11 can independently control the normal operation of the negative pressure device 8 , the water pump 7 and the light source 10 .

[0035] During use, when flushing is required, the control switch 11 is started to control the button of the water pump 7. At this time, the water pump 7 discharges the liquid in the liquid storage device 9 through the second flushing channel 6 and the first flushing channel 3. When smoke or blood is generated during use, the control switch 11 is started to control the button of the negative pressure device 8, and the blood or smoke is discharged through the first suction pipe 4 and the second suction pipe 5. When lighting is needed, the control switch 11 is started to control the switch of the light source 10.

[0036] The hook body of the retractor is made of a transparent acrylic light-guiding plate, which fully exposes the surgical field of view. The light source of the handle can guide light through the structure to illuminate small cavities, making it convenient for doctors to operate during surgery. The front end of the hook body has a suction channel opening and a flushing channel opening, which can promptly absorb the smoke and accidental bleeding generated by the electric knife during surgery, further fully exposing the surgical field and facilitating doctors' operations.

[0037] Since smoke is generally light in weight and has a certain temperature after it is generated, it will rise after it is generated, while the blood generated will only be on the patient's skin. There is a difference in the distribution range of smoke and blood, so the smoke and blood need to be absorbed and processed separately.

[0038] Specifically, Figure 3-4 As shown, a plurality of suction holes 12 are formed on the surface of one end of the hook body 1 away from the handle 2 , and each of the suction holes 12 is connected to the first suction pipe 4 , so that gas is introduced from the suction holes 12 into the first suction pipe 4 .

[0039] The first suction pipe 4 sucks blood, and the suction hole 12 sucks gas smoke. Since the blood and the gas smoke will eventually converge in the first suction pipe 4, a flow control device needs to be set for the blood and the gas smoke to flow back.

[0040] Specifically, Figure 3-4 As shown, the inner cavity of the first suction pipe 4 located below the suction hole 12 and the inner cavity of each suction hole 12 are provided with a one-way valve 13. Under the control of the one-way valve 13, the first suction pipe 4 can only suck blood in one direction, and the suction hole 12 can only take in air.

[0041] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
