Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a waterproof surgical mainframe housing. Background Art

[0002] When a doctor uses an electrosurgical / ultrasonic scalpel surgical system for minimally invasive surgery, it is necessary to connect a surgical device mainframe to supply energy to the electrosurgical / ultrasonic scalpel. In order to provide reliable and stable energy, the surgical device mainframe needs to maintain the safety and stability of its internal components. During actual operation, there is water splash, and it is easily affected by dripping water in the external environment during testing. Moreover, since the mainframe is usually made of sheet metal, condensation water is likely to be generated due to temperature changes in its material. All these will cause the mainframe to have a risk of water leakage. Therefore, the housing of the surgical device mainframe still needs to have the functions of shock resistance and waterproofing.

[0003] However, the probability of the mainframe housing being impacted by a large amount of water flow is relatively low. If a high-level waterproof structure is set, it will not only increase the assembly difficulty and inconvenience of the mainframe, but also increase the additional cost. At the same time, due to the weak straightening property of the sheet metal, it is difficult to provide a consistent pressing force at its joints. Therefore, gaps are likely to occur at the joints of the mainframe, making it difficult to tightly press the sealing ring to form a complete seal. Therefore, how to set a reasonable waterproof structure for the mainframe housing is a problem that needs to be solved. Summary of the Utility Model

[0028] As Figures 1 to 4 shown, the present utility model discloses a waterproof surgical mainframe housing, including a front cover 1, an outer housing 2, and an inner housing 3 that can be assembled together. The inner housing 3 is placed inside the outer housing 2, and the front end of the inner housing 3 is fixedly connected to the front cover 1, and the rear end thereof is fixedly connected to the outer housing 2 to form an integral body. The front end side of the outer housing 2 is engaged with the rear end side of the front cover 1, and a water guide groove 201 is provided along the upper side of the front end of the outer housing 2. The front side of the water guide groove 201 is an opening 202. The upper side of the rear end of the front cover 1 is inserted into the opening 202 and engaged with the upper side of the front end of the outer housing 2. The gap at the connection between the upper sides of the outer housing 2 and the front cover 1 is directly opposite to the water guide groove 201. A water delivery channel 100 that is docked with both ends of the water guide groove 201 is formed between the two sides of the outer housing 2 and the inner housing 3 to allow the water in the water guide groove 201 to flow out.

[0029] In this solution, a water guide groove 201 that can hold water is provided at the connection between the upper sides of the outer housing 2 and the front cover 1 where water leakage is likely to occur, to collect dripping water and at the same time transport the dripping water into the gap between the two sides of the outer housing 2 and the inner housing 3 to form the water delivery channel 100, so as to discharge the accumulated water in the water guide groove 201 out of the housing in real time. It can not only prevent water droplets from dripping into the mainframe, but also does not require other waterproof structures, achieving the required IPX1 waterproof level, ensuring convenient assembly of the housing while effectively controlling costs.

[0030] Specifically, as Figure 3As shown in the figure, a stepped surface 101 adapted to the front edge side of the outer housing 2 is formed on the rear edge side of the front cover 1 to be snap-connected to the upper front edge side of the outer housing 2. Moreover, a beveled surface 102 is provided at the bottom of the upper rear edge side of the front cover 1 so that its thickness gradually decreases from front to back. The width of the opening 202 is not greater than the maximum thickness of the upper rear edge side of the front cover 1. Such a structure enables the upper rear edge side of the front cover 1 to be tightly fitted with the opening 202 after being inserted into the opening 202, preventing water leakage at the opening 200 and enhancing the snap connection stability between the front cover 1 and the outer housing 2 at the same time.

[0031] Preferably, the cross-section of the water guide groove 201 is U-shaped or V-shaped. In other feasible embodiments, the inner wall of the water guide groove 201 may be inclined from the middle to both ends to form a further water guiding effect.

[0032] As Figure 2 and Figure 3 As shown in the figure, the two rear side edges of the front cover 1 are snap-fitted with the two front side edges of the outer housing 2. Moreover, at least a pair of elastic buckles 203 are symmetrically arranged on the inner walls of the two front side edges of the outer housing 2. The elastic buckles 203 are bent to form an elastic opening with a clamping force. The two rear side edges of the front cover 1 are respectively inserted into the corresponding elastic openings, so that the elastic buckles 203 limit the positions of the two rear side edges of the front cover 1. The elastic buckles 203 can ensure the connection tightness between the two sides of the front cover 1 and the outer housing 2. And during the actual installation process, the front cover 1 is first fixedly connected to the front end of the inner housing 3, and then the inner housing 3 is inserted into the outer housing 2 for fixation. Therefore, the arrangement of the elastic buckles 203 can also play a role of pre-positioning to facilitate the subsequent fixing operation between the outer housing 2 and the inner housing 3.

[0033] The two sides of the inner housing 3 are fixedly connected to the two rear side edges of the front cover 1 by screws. A gap that can communicate with the outside is formed between the two sides of the inner housing 3 and the two sides of the outer housing 2. The gap is the water delivery channel 100.

[0034] Preferably, a gap not greater than the width of the water delivery channel 100 is formed between the two ends of the water guide groove 201 and the two side walls of the outer housing 2. And water guide strips 204 that abut against the two ends of the water guide groove 201 are convexly provided on the inner walls of the two sides of the outer housing 2. The water guide strips 204 introduce the water in the water guide groove 201 into the water delivery channel 100.

[0035] Further, the water guide strip 204 extends obliquely from the end of the water guide groove 201 towards the inner wall of the outer housing 2. An outwardly convex water guide strip 204 is provided to dock with both ends of the water guide groove 201. Utilizing the characteristic of fluid adhering to the wall, the water flow in the water guide groove 201 is introduced into the water conveyance channel 100, avoiding unnecessary splashing caused by natural dripping of the water flow, and ensuring that the water in the water guide groove 201 does not drip into the inner housing.

[0036] In other feasible embodiments, a concave strip structure can also be provided on the inner wall of the outer housing 2 to replace the water guide strip 204 to form a water guiding function.

[0037] Support feet 301 are provided at the bottom of the inner housing 3, making the bottom of the inner housing 3 suspended, ensuring that the water conveyance channel 100 is connected to the outside to drain water, and avoiding internal seepage caused by water accumulation at the bottom of the inner housing 3.

[0038] A set of connecting pieces 205 are provided on the rear side edge of the outer housing 2, which are wrapped around the rear end face of the inner housing 3, and the connecting pieces 205 are fixedly connected to the rear end face of the inner housing 3 by screws.

[0039] Further, the upper part of the rear upper side of the outer housing 2 and the upper halves of the two side edges connected thereto protrude outward from the rear end face of the inner housing 3 to form a water retaining shed 206. The setting of the water retaining shed 206 can prevent the accumulated water on the top of the outer housing 2 from flowing into the interior from its rear end, further enhancing the waterproof effect of the entire housing.
