Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments and equipment, relates to a surgical aspirator structure, and in particular to a thoracic surgical aspirator tube head. Background Art

[0002] The suction device is used to remove bleeding, exudate, pus, and contents of chest organs during surgery to make the surgery clear and reduce the chance of contamination. The principle of the suction device is very simple, that is, to create a negative pressure state of its suction head through a certain method, so that the atmospheric pressure will squeeze the substances outside the suction head into the suction head, thereby achieving the "suction" effect.

[0003] The suction device mainly includes a negative pressure chamber and a suction tube. The negative pressure chamber generally uses a motor to drive a turbine to generate negative pressure, and the suction tube directly acts on the body to attract exudates. At present, the suction tube mainly uses a pipe. When there is exudate such as blood, the tube head is contacted with the exudate for suction. The use effect is good, but there are also many disadvantages. In order to prevent adsorption damage to the organs, the pressure of the suction device is not very high, and the exudate is prone to reflux in the pipe. The pipe is always in a suction state, and there are factors that cause misaspiration.

[0004] Application number: 2023217174306, discloses a surgical suction head structure, including a tube body and a clamping ring sleeve, a handle is fixedly installed at the bottom of the clamping ring sleeve, a hard tube is fixedly installed on the back of the tube body, a limit sleeve is fixedly installed on the back of the inner cavity of the clamping ring sleeve, and support plates are fixedly installed on both sides of the top of the clamping ring sleeve. In the utility model, through the setting of the handle, it can be directly convenient for doctors to hold it, and through the setting of the clamping ring sleeve, it can be fixed and clamped for tubes of different thicknesses, and the fixing gap of the buckle can be adjusted by tightening the bolt, thereby ensuring the fixing effect of the clamping ring sleeve on the tube body, and at the same time, it can ensure that after holding the handle, the suction work can be easily carried out, and the tube body, soft tube and connecting hose will not be bent, thereby ensuring the progress of the operation.

[0005] In the above scheme, a handle is added, which has a better fixing and holding effect, but the suction of the tube head cannot be opened and closed freely, and the factor of mis-aspiration still exists.

[0006] In the prior art, the suction tube head has the technical problem of easily causing accidental aspiration. Utility Model Content

[0010] Furthermore, the front end of the membrane flap is inclined upward by 3-5 degrees.

[0011] Furthermore, the vertical cross section of the control ball is elliptical, and the transverse cross section is spherical or elliptical.

[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the utility model, it is obvious that the embodiments described below are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of 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.

[0025] Embodiment 1, according to Figure 1-5 A thoracic surgery suction tube head, which includes a front branch 1, a control ball 2, a rear branch 3 and a conversion joint 4 connected in sequence; the control ball 2 is an elastic ball; the two ends of the elastic ball are respectively connected to the front branch and the rear branch; a pair of relatively distributed semicircular membrane flaps 5 are arranged in the control ball 2; the membrane flaps are elastic; the front edges of the pair of membrane flaps are elastically fitted; the membrane flaps are located between the control ball and the connection between the front branch and the rear branch.

[0026] The front end of the membrane flap is tilted upward by 3-5 degrees, and the front end refers to the direction of the center of the circle. When held, it can be kept open upward without backflow.

[0027] according to Figure 2-3 The vertical cross section of the control ball is elliptical, and the transverse cross section is spherical or elliptical.

[0028] according to Figure 4 The outer periphery of the control ball is provided with a vertical raised strip 6. The raised strip 6 can increase the strength, prevent the negative pressure bin from being adsorbed and deformed, and can also increase the friction of the handheld.

[0029] The outer side of the control ball is provided with a hand-grip mark or a color-marked grip position. The main purpose of marking the grip position is to apply force in the direction located at both ends of the membrane flap fitting line, so that the membrane flap can open a gap of appropriate size according to the force.

[0030] according to Figure 5 The front branch is provided with a bending portion 7. The bending portion changes the suction angle between the hand-held part and the body suction part, making it more convenient to use.

[0031] The conversion joint is connected to the suction device through a soft pipe. The conversion joint is a connector, one end of which is sealed and connected to the rear branch pipe 3, and the other end is sealed and connected to the hose.

[0032] The control ball and the membrane petal are made of transparent silicone material, and the front branch pipe and the rear branch pipe are made of transparent material.

[0033] The control ball 2 is connected to the front branch pipe 1 and the rear branch pipe 3. The front branch pipe 1 and the rear branch pipe 3 are provided with raised or recessed grooves, and the two ends of the control ball are elastically clamped or sleeved.

[0034] In Embodiment 2, the suction device is provided with a plurality of tube heads, and the lengths of the front branches 1 and the angles of the bending portions 7 of the plurality of tube heads are different.

[0035] Example 3: When in use, hold the control ball and squeeze it, the control ball will be deformed, the membrane flap inside will open, and negative pressure suction will begin. After the body exudates are sucked clean, release the control ball, the membrane flap will close, and the suction will stop. It will not cause accidental aspiration when not in use.

[0036] The advantages of this application are:

[0037] No other separate parts, no precision parts, and extremely low damage rate;

[0038] All can be cleaned and disinfected at high temperature;

[0039] One-handed operation;

[0040] Visualization of the situation inside the tube head.

[0041] After the application is closed, in order to prevent the negative pressure chamber from working uniformly, pressure sensors and other components can be added for control. These structures are common in the mechanical field and will not be described in detail.

[0042] In the present application, a control ball is added, and during use, it is held to open the suction, and closed after being released, which effectively solves the technical problem of the hidden danger of accidental inhalation in the prior art.
