Description

Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary instruments, in particular to a thoracoscopic lens fixer. Background Art

[0002] Thoracoscopic surgery is a representative operation of minimally invasive thoracic surgery. Thoracoscopic surgery (video-assisted thoracoscopic surgery) uses modern television camera technology and high-tech surgical instruments and equipment.

[0003] During thoracoscopic surgery, the scope holder is usually required to support the thoracoscopic tube. However, with the continuous development of minimally invasive surgery, the requirements for scope holders in thoracoscopic surgery have become more stringent. The surgery not only requires the scope holder to adjust the lens distance, focal length, angle and clarity in a timely and accurate manner according to the surgeon's needs and surgical details, but also requires the scope holder to avoid collision with the instrument as much as possible to provide the surgeon with maximum operating space.

[0004] For example, in the prior art, a Chinese patent with patent announcement number CN217659806U discloses a single-port thoracoscopic fixator, which can avoid congestion when a thoracoscope and operating instruments are used together, and does not require frequent adjustment of the position and layout of the thoracoscope and instruments, thus providing more incision level operating space for the surgeon.

[0005] However, when the position and layout of the thoracoscope is occasionally adjusted, the position of the fixator is adjusted by toggling the fixator, causing the ball to roll in the sliding groove and causing the fixator to slide on the fixing ring. However, when the fixator is toggled, the anti-slip pattern will contact the fixing ring, making it difficult to move the fixator and even causing the fixing ring to move, affecting the normal progress of the operation. Utility Model Content

[0006] The utility model aims to provide a thoracoscopic lens holder, which is convenient for fixing the thoracoscopic lens and adjusting the position of the thoracoscopic lens on the fixing ring, and has high practicality.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A thoracoscopic lens holder comprises a fixing ring, a plastic spring buckle is installed on the upper surface of the fixing ring, a fixing rope is arranged on the plastic spring buckle, and a sliding assembly is fixedly arranged on the bottom of the plastic spring buckle;

[0009] The fixing ring includes an annular through groove and an annular inner groove. The center of the upper surface of the fixing ring is provided with an annular through groove, and the bottom of the annular through groove is provided with an annular inner groove.

[0010] The sliding assembly includes a rubber disc, a fixing column, a metal ring and a sleeve spring. A fixing column is fixedly arranged at the center of the upper surface of the rubber disc, and the fixing column is fixedly arranged on the bottom surface of the plastic spring buckle. A metal ring is penetrated above the fixing column, and a sleeve spring is fixedly arranged between the upper surface of the metal ring and the bottom surface of the plastic spring buckle.

[0011] Furthermore, the plastic spring buckle is a double-hole spring buckle, and the two ends of the fixing rope pass through the double holes of the plastic spring buckle in sequence.

[0012] Furthermore, the width of the annular through groove is smaller than the width of the annular inner groove.

[0013] Furthermore, the diameter of the fixing column is equal to the width of the annular through-groove, and the fixing column penetrates the annular through-groove.

[0014] Furthermore, the metal ring is attached to the top of the fixing ring, and the rubber disc is in the annular inner groove, and the sleeve spring is in a compressed state.

[0015] Furthermore, the thickness of the rubber disk is smaller than the depth of the annular inner groove.

[0016] Furthermore, the bottom surface of the metal ring and the upper surface of the fixing ring are polished, and the upper surface of the rubber disc is provided with a frosted layer.

[0017] Furthermore, a ball bearing is rollingly arranged on the bottom surface of the metal ring.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model places a fixing ring around the surgical incision, passes the thoracoscope tube through the ring formed by the fixing rope and the plastic spring buckle, and then presses the button on the plastic spring buckle to tighten the fixing rope to achieve the effect of tightening the thoracoscope tube for fixing.

[0020] 2. When the utility model adjusts the position and layout of the thoracoscopic tube, by pressing the plastic spring buckle, the plastic spring buckle drives the fixing column to move downward, the sleeve spring is in a re-compressed state, the fixing column drives the rubber disc to move downward, the rubber disc does not contact the upper surface of the annular inner groove, and the friction is reduced. The metal ring slides on the fixing ring, and the position of the plastic spring buckle is conveniently adjusted to achieve the effect of adjusting the position of the thoracoscopic tube. After the plastic spring buckle is released, the rebound force of the sleeve spring causes the fixing column and the rubber disc to move upward, and the frosted layer on the rubber disc contacts the upper surface of the annular inner groove, increasing the friction between the sliding component and the annular inner groove, achieving the effect of fixing the sliding component, thereby achieving the effect of positioning the plastic spring buckle position of the thoracoscopic tube.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a thoracoscopic lens holder, comprising a fixing ring 1, a plastic spring buckle 2 is installed on the upper surface of the fixing ring 1, a fixing rope 3 is arranged on the plastic spring buckle 2, and a sliding component is fixedly arranged on the bottom of the plastic spring buckle 2;

[0036] The fixing ring 1 includes an annular through groove 101 and an annular inner groove 102. The center of the upper surface of the fixing ring 1 is provided with an annular through groove 101, and the bottom of the annular through groove 101 is provided with an annular inner groove.

[0037] The sliding assembly includes a rubber disc 4, a fixing column 401, a metal ring 402 and a sleeve spring 403. The fixing column 401 is fixedly arranged at the center of the upper surface of the rubber disc 4, and the fixing column 401 is fixedly arranged on the bottom surface of the plastic spring buckle 2. The metal ring 402 is penetrated above the fixing column 401, and the sleeve spring 403 is fixedly arranged between the upper surface of the metal ring 402 and the bottom surface of the plastic spring buckle 2.

[0038] During surgery, the fixing ring 1 is placed around the surgical incision, and the thoracoscopic tube is passed through the ring formed by the fixing rope 3 and the plastic spring buckle 2. Then, the button on the plastic spring buckle 2 is pressed to tighten the fixing rope 3 to achieve the effect of tightening the thoracoscopic tube.

[0039] During the operation, the thoracoscopic tube may occasionally change its position and layout. By pressing the plastic spring buckle 2, the plastic spring buckle 2 drives the fixed column 401 to move downward, and the sleeve spring 403 is in a re-compressed state. The fixed column 401 drives the rubber disk 4 to move downward, and the rubber disk 4 does not contact the upper surface of the annular internal groove 102, thereby reducing the friction. The metal ring 402 slides on the fixed ring 1, which facilitates the adjustment of the position of the plastic spring buckle 2, thereby achieving the effect of adjusting the position of the thoracoscopic tube. After loosening the plastic spring buckle 2, the rebound force of the sleeve spring 403 causes the fixed column 401 and the rubber disk 4 to move upward, and the frosted layer on the rubber disk 4 contacts the upper surface of the annular internal groove 102, thereby increasing the friction between the sliding component and the annular internal groove 102, thereby achieving the effect of fixing the sliding component, thereby achieving the effect of positioning the plastic spring buckle 2 at the position of the thoracoscopic tube.

[0040] In this embodiment, the plastic spring buckle 2 is a double-hole spring buckle, and the two ends of the fixing rope 3 pass through the double holes of the plastic spring buckle 2 in sequence, so that the fixing rope 3 and the plastic spring buckle 2 form an annular through hole, which facilitates the fixing rope 3 to fix the thoracoscopic tube.

[0041] In this embodiment, the width of the annular through groove 101 is smaller than the width of the annular inner groove 102 .

[0042] In this embodiment, the diameter of the fixing column 401 is equal to the width of the annular through groove 101 , and the fixing column 401 penetrates the annular through groove 101 , so that the fixing column 401 can slide along the annular through groove 101 .

[0043] In this embodiment, the metal ring is attached to the top of the fixing ring 1, and the rubber disk 4 is in the annular inner groove 102. The sleeve spring 403 is in a compressed state, so that the rubber disk 4 is attached to the upper surface of the annular inner groove 102, thereby achieving the effect of positioning the sliding component.

[0044] In this embodiment, the thickness of the rubber disk 4 is smaller than the depth of the annular inner groove 102 , which facilitates the rubber disk 4 to move downward along the annular inner groove 102 and prevents the rubber disk 4 from contacting the annular inner groove, thereby reducing the friction between the sliding assembly and the fixing ring 1 .

[0045] In this embodiment, the bottom surface of the metal ring 402 and the upper surface of the fixing ring 1 are polished, and the upper surface of the rubber disk 4 is provided with a frosted layer, so as to reduce the friction between the metal ring 402 and the upper surface of the fixing ring 1, facilitate the metal ring 402 to slide along the upper surface of the fixing ring 1, and increase the friction between the rubber disk 4 and the upper surface of the annular internal groove 102, so as to achieve the effect of positioning the sliding component on the fixing ring 1.

[0046] In this embodiment, a ball 404 is rolled on the bottom surface of the metal ring 402 , and the ball 404 rolls on the upper surface of the fixing ring 1 , further reducing the friction between the metal ring 402 and the fixing ring 1 , making it easier to adjust the position of the sliding component on the fixing ring 1 .

[0047] In this embodiment, a clamping groove 5 is further provided at the bottom end of the fixing ring 1 , and the clamping groove 5 can be used to install the fixing ring 1 and the protective cover.
