Description

Technical Field

[0001] This application relates to the field of surgical aids technology, and in particular to a lung-blocking device for thoracic surgery. Background Technology

[0002] In thoracic surgery, surgical treatment is a common approach. However, in some cases, lung tissue can obstruct the procedure. For example, during thymoma surgery, the expansion and contraction of the lung within the thoracic cavity can obstruct the surgeon's view of the thymoma and affect their operation. Therefore, clinicians often use oval forceps to hold a piece of gauze to cover the lung lobe, thus fully exposing the area to be operated on. This method is particularly inconvenient for minimally invasive surgeries, increasing the difficulty of the procedure. To address this issue, a lung-covering device for thoracic surgery is proposed to solve these technical problems. Utility Model Content

[0003] One of the objectives of this application is to provide a lung-blocking device for thoracic surgery.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a lung-blocking device for thoracic surgery, comprising a cylinder, a handle assembly, and a connecting rod assembly. The handle assembly is installed at the first end of the cylinder, and the connecting rod assembly is a foldable structure. The connecting rod assembly is disposed at the second end of the cylinder and cooperates with the handle assembly. When blocking the lung, the second end of the cylinder is adapted to penetrate into the patient's body through the handle assembly, and the handle assembly is adapted to drive the connecting rod assembly to unfold.

[0005] Preferably, the linkage assembly includes a drive rod, a pair of transmission rods, and a pair of stop rods. The stop rods are hinged to the second end of the cylinder and symmetrically distributed. The first end of the transmission rod is hinged to the stop rod. The drive rod is slidably disposed within the cylinder and its first end engages with the handle assembly. The second end of the drive rod is hinged to the transmission rod. The handle assembly is adapted to drive the drive rod to slide, thereby driving the stop rods to rotate relative to each other via the transmission rods, so as to realize the expansion or contraction of the linkage assembly.

[0006] Preferably, a flexible layer is provided between the two blocking rods; when the blocking rods are deployed, the flexible layer cooperates with the blocking rods to form a blocking part.

[0007] Preferably, the flexible layer is gauze, the blocking rod is provided with a slot, and the two ends of the gauze are detachably connected to the slot.

[0008] Preferably, the handle assembly includes a first scissor handle and a second scissor handle. The first scissor handle is fixedly installed at the first end of the cylinder, and the second scissor handle rotates with the first scissor handle to form a cross structure. The second scissor handle is adapted to rotate around the first scissor handle and pass through the first end to push the blocking rod to slide.

[0009] Preferably, the first shear handle is connected to the first end of the cylinder via a first end, and the two are perpendicular to each other.

[0010] Preferably, the first end of the second shear handle is provided with a locking block, and the outside of the blocking rod is provided with a locking groove, the locking block and the locking groove cooperating with each other.

[0011] Preferably, the first scissor handle and the second scissor handle are engaged by a limiting component; the limiting component is adapted to lock the second scissor handle so that the linkage assembly remains in the adjusted state.

[0012] Preferably, the limiting component includes a rack and a toothed block that cooperate with each other. The rack is installed on the first scissor handle and passes through the second scissor handle, and the toothed block is elastically and movably installed on the second scissor handle. The toothed block is adapted to engage with the rack under elastic force, thereby locking the second scissor handle.

[0013] Preferably, the first scissor handle and the second scissor handle are connected by an elastic element; after blocking, the linkage assembly is adapted to remain in a retracted state under the action of the elastic element.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This utility model features a foldable linkage assembly, a cylindrical body, and a handle assembly. Especially when entering a micro-incision, the folded linkage assembly can be inserted more smoothly.

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] One preferred embodiment of this application, such as Figures 1 to 6 As shown, a lung-blocking device for thoracic surgery includes a cylinder 1, a handle assembly 2, and a connecting rod assembly 3. The handle assembly 2 is installed at the first end (right end) of the cylinder 1, while the connecting rod assembly 3 is located at the second end (left end) of the cylinder 1 and cooperates with the handle assembly 2. The connecting rod assembly 3 has a foldable structure.

[0027] Understandably, during the surgical procedure, medical staff operate the lung-blocking device using handle assembly 2, then vertically position the cylinder 1 and insert its second end into the patient's body. It should be noted that at this time, the connecting rod assembly 3 is folded and retracted at the second end of the cylinder 1, thus not interfering with insertion into the incision. Once inserted to a suitable position close to the lung, handle assembly 2 is operated, causing the connecting rod assembly 3 to unfold. The unfolded connecting rod assembly 3 effectively blocks the opening of the lung lobe, protecting lung tissue and clearly exposing the surgical field, facilitating the surgeon's operation.

[0028] This application does not specifically limit the structure of the linkage assembly 3, but the following specific embodiment is provided for reference:

[0029] like Figure 2 As shown, the linkage assembly 3 includes a drive rod 301, a pair of transmission rods 302, and a pair of blocking rods 303. The blocking rods 303 are hinged to the second end of the cylinder 1 and are symmetrically distributed. The first end of the transmission rod 302 is hinged to the blocking rod 303. The drive rod 301 is slidably disposed inside the cylinder 1 and its first end (right end) cooperates with the handle assembly 2. The second end (left end) of the drive rod 301 is hinged to the transmission rod 302.

[0030] Understandably, after being inserted into the patient's body, medical personnel use the handle assembly 2 to drive the drive rod 301 to slide. The drive rod 301 acts on the blocking rod 303, which in turn acts on the transmission rod 302 to rotate relative to it. For example, as... Figure 2 As shown, when the drive rod 301 moves to the right, the drive rod 301 will act on the two blocking rods 303 through the transmission rod 302 to rotate relatively away, thereby realizing the unfolding of the connecting rod assembly 3; similarly (not shown), when the drive rod 301 moves to the left, the two blocking rods 303 will rotate relatively close together until they are folded and retracted at the second end of the cylinder 1, that is, the two blocking rods 303 and the cylinder 1 are parallel or nearly parallel, thus making the blocking rods 303 and the cylinder 1 form a straight structure, which facilitates insertion through the patient's (micro) wound.

[0031] Based on the above embodiments, we know that the unfolding of the linkage assembly 3 is the rotation and unfolding of the two blocking rods 303. After unfolding, it forms an "eight" shape. The larger the distance between the two blocking rods 303, the larger the blocking range. However, the blocking effect is reduced at this time. Therefore, there is no blocking between the two blocking rods 303.

[0032] Therefore, in order to solve the above-mentioned technical problems, in one embodiment of this application, such as Figure 1As shown, a flexible layer 4 can be provided between the two blocking rods 303. It should be understood that when the blocking rods 303 are unfolded, the flexible layer 4 cooperates with the blocking rods 303 to form a blocking section, thus providing a good barrier against the lungs. Of course, when the blocking rods 303 are folded and retracted, the flexible layer 4 will also deform and retract accordingly.

[0033] Specifically, for example, the flexible layer 4 can be made of gauze 401; and for ease of installation, such as Figure 3 As shown, a strip groove 5 can be provided on the blocking rod 303, and the two ends of the gauze 401 are detachably connected to the strip groove 5.

[0034] Understandably, gauze 401 can also be specially manufactured with creases, and its shape and size are adapted to the blocking rod 303. During installation, both ends of gauze 401 are inserted into the two slots 5. Multiple bolts can be installed on the blocking rod 303, and tightening these bolts limits and fixes the ends of gauze 401. During shrinking and folding, gauze 401 can be folded and folded in an orderly manner through the creases, thus preventing it from becoming tangled during the folding process. Of course, the specific shape of gauze 401 can also be cut and used by medical personnel according to the actual situation.

[0035] Therefore, by making gauze 401 detachable, medical staff can remove and replace gauze 401, thus enabling the lung-blocking device for thoracic surgery to be reused repeatedly, and also facilitating the cleaning of the lung-blocking device.

[0036] In one embodiment of this application, such as Figure 4 As shown, the handle assembly 2 includes a first scissor handle 201 and a second scissor handle 202. The first scissor handle 201 is fixedly installed at the first end of the cylinder 1, and the second scissor handle 202 rotates with the first scissor handle 201 to form a cross structure (i.e., a scissor structure).

[0037] It is understandable that the first shear handle 201 can be regarded as "fixed" at this time, and the cylinder 1 can be moved by holding the first shear handle 201. The second shear handle 202 can be regarded as "movable", that is, the second shear handle 202 can rotate around the first shear handle 201. At this time, the first end of the second shear handle 202 can push the blocking rod 303 to slide.

[0038] Specifically, the engagement between the first end of the second shear handle 202 and the blocking rod 303 is as follows: Figure 5As shown, a locking block 8 is provided at the first end of the second scissor handle 202, and a locking groove 9 is provided on the outside of the blocking rod 303. The locking block 8 and the locking groove 9 cooperate with each other. It should be noted that the volume of the groove inside the locking groove 9 is larger than that of the locking block 8, because the locking block 8 rotates rather than translates under the action of the second scissor handle 202. Therefore, the locking groove 9 must provide sufficient clearance for the movement of the locking block 8.

[0039] Furthermore, to facilitate operation of the cylinder 1 and to prevent it from obstructing the wound after being inserted into the body, the first end of the cylinder 1 can be vertically mounted on the first end of the first scissor handle 201. This means the entire handle assembly 2 is perpendicular to the cylinder 1. Essentially, the handle assembly 2 is offset from the top of the wound. This allows medical personnel to more easily insert other medical instruments through the wound during surgery, reducing accidental contact and obstruction, and improving surgical efficiency and safety. Simultaneously, when the cylinder 1 is in a vertical position, the movable second scissor handle 202 is also located above the first scissor handle 201, making it easier and less strenuous to press and rotate the second scissor handle 202.

[0040] Of course, after the second scissor handle 202 is operated to rotate and unfold the blocking rod 303, medical personnel need to continuously apply pressure to the second scissor handle 202 to maintain this state, which is time-consuming and labor-intensive. Therefore, in this embodiment, as... Figure 5 As shown, the first scissor handle 201 and the second scissor handle 202 can be engaged by the limiting component 7. It can be understood that the limiting component 7 can lock the second scissor handle 202 so that the linkage assembly 3 (i.e., the blocking rod 303) remains in the adjusted state.

[0041] Specifically, the limiting component 7 includes a rack 701 and a toothed block 702 that cooperate with each other. The rack 701 is installed on the first scissor handle 201 and passes through the second scissor handle 202. Of course, the rack 701 is preferably arc-shaped, so as to match the arc-shaped path of the second scissor handle 202 when it rotates. The toothed block 702 is elastically and movably installed on the second scissor handle 202.

[0042] Understandably, when the toothed block 702 is not subjected to any external force, the teeth between the toothed block 702 and the rack 701 engage under the action of elasticity, thereby locking the second scissor handle 202. To unlock, simply move the toothed block 702 away from the rack 701 by hand.

[0043] Of course, there are several ways to install the toothed block 702, including but not limited to the following two: Method 1, the toothed block 702 is elastically rotated and installed at the second scissor handle 202 by a torsion spring. Method 2, the toothed block 702 is slidably installed at the second scissor handle 202 by a spring.

[0044] We know that in the "scissor-type" handle assembly 2, the second scissor handle 202 can be easily and conveniently rotated by pressing. However, when the linkage assembly 3 retracts, the second scissor handle 202 needs to be operated to reverse and reset. Of course, this is not as convenient as pressing, but the toothed block 702 also needs to be moved to unlock, which makes the reset of the second scissor handle 202 more inconvenient.

[0045] Therefore, in order to solve the above problems, such as Figure 4 As shown, the first shear handle 201 and the second shear handle 202 can be connected by an elastic element 6. It can be understood that when the second shear handle 202 is pressed to rotate, the elastic element 6 is in a compressed, energy-storing state; and when the force applied to the second shear handle 202 is reduced or eliminated, the second shear handle 202 will automatically reverse and reset under the action of the elastic element 6, thus making it easier to operate the device. Simultaneously, the connecting rod assembly 3 can also remain in a contracted state under the action of the elastic element 6.

[0046] It should be noted that the elastic element 6 can have various structural forms; for example, it can be a spring. Figure 4 As shown, the elastic element 6 can be an elastic metal strip with an arc-shaped structure, located between the first shear handle 201 and the second shear handle 202.

[0047] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
