Description

Technical Field

[0001] The present invention relates to a method and device for measuring the volume of a body surface tumor. Background Art

[0002] In oncology research, generally, for the evaluation of tumor size, the longest side L of the tumor is first determined, then the longest short side in the direction perpendicular to L is visually observed, and then the short side W is measured. The volume size is evaluated by measuring L and W. Sometimes, the tumor volume is further calculated through the formula TV = 1 / 2 * L * W * W. However, in the measurement of the short side, the position of the short side cannot be accurately determined and needs to be determined by the naked eye, which will cause a large error. To reduce the error, existing devices such as "CN214537655U - An in vitro tumor volume accurate measurement device" or "CN2735945Y - An in vitro tumor volume accurate measurement device" are used to measure the volume of the tumor after cutting, or three-dimensional modeling is carried out through the placement of silicone indentation after cutting, and then the volume is calculated. However, it is not applicable to body surface tumors. For benign tumors located on the body surface, when the tumor burden is small, it has little impact on human health and there is no need for surgery temporarily. Regular follow-up reviews are given. When the tumor grows rapidly or is accompanied by symptoms such as pain and is vigilant for malignancy, surgical intervention is required. A considerable part of malignant tumors located on the body surface are inoperable or do not require surgical intervention, such as some "cutaneous malignant tumors with visceral metastases" and "other malignant tumors metastasizing to the skin surface with extensive metastases in other organs". Surgical resection of the local skin metastasis focus in these patients cannot cure the tumor. After systemic chemotherapy and local radiotherapy, accurate measurement of the tumor volume is also helpful for analyzing the condition. Therefore, an accurate and convenient method for monitoring the volume of body surface tumors is of great significance for analyzing the growth of benign and malignant tumors, assisting in decision-making on the surgical timing, and understanding the condition. Existing methods for measuring body surface tumors have many limitations, such as: ① Imaging methods such as magnetic resonance cannot image small-volume body surface tumors. ② And if the tumor shape is irregular, it will be very difficult to calculate the tumor volume using the formula. ③ Some non-imaging measurement devices mostly measure body surface tumors in the way of "after tumor resection and in vitro", which is not applicable to the population mentioned above (this population needs a "non-in vitro" measurement method for non-surgically removed body surface tumor volume). ④ Some measurement methods use computer three-dimensional modeling to calculate the volume of body surface tumors, which is time-consuming and laborious, and lacks the support of big data and corresponding verification. Therefore, there is an urgent need for a "non-in vitro" measurement method for the volume of body surface tumors. If this device can be applied conveniently, measured accurately, efficiently, and at a lower cost than three-dimensional modeling for volume measurement, it will have great advantages and application prospects.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further descriptions of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0019] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] As Figures 1-6 shown, a method for measuring the volume of a body surface tumor includes the following steps: Step 1) Stick a marking sticker on the outer periphery of the measurement area on the body surface; Step 2) Apply an elastomeric impression material to the measurement area through a glue gun, and the area of the elastomeric impression material is larger than the measurement area to avoid the elastomeric impression material not completely covering the measurement area; Step 3) The elastomeric impression material solidifies and detaches from the body surface to form a measuring plate with a tumor relief groove; Step 4) Cut the measuring plate and measure the length and width dimensions of the tumor relief groove; Step 5) Place the tumor relief groove of the measuring plate facing upwards and fix it; Step 6) Weigh the syringe filled with water; Step 7) Inject the water in the syringe into the tumor accommodation groove until the tumor accommodation groove is filled; Step 8) Weigh the syringe with the remaining water; Step 9) Calculate the weight of the water injected into the tumor accommodation groove and convert it into the tumor volume. The conversion method uses the conversion of the weight and volume of water, and then the tumor volume is obtained.

[0021] In this embodiment, the marking sticker is used to mark the edge of the tumor. At the same time, when the elastomeric impression material solidifies and detaches from the body surface, the marking sticker adheres to the measuring plate, facilitating the subsequent measurement of the length and width of the tumor accommodation groove.

[0022] In this embodiment, the elastomeric impression material in step 2) is a polyaddition type silicone rubber impression material.

[0023] In this embodiment, a cross nail is provided at the notch of the tumor accommodation groove in step 5). The cross nail is used to observe the completion of the filling of the tumor accommodation groove after filling with water.

[0024] A device for measuring the volume of a tumor on the body surface: including a workbench 1, a clamping mechanism 2, a cutting device 3, and a weighing device 4 are arranged on the workbench. The weighing device can use an existing weighing scale. A measuring plate 5 is placed on the cutting device. The measuring plate is formed by the elastomeric impression material solidifying and detaching from the body surface, forming a measuring plate with a tumor accommodation groove 40. A syringe 6 is arranged on the weighing device, and the syringe is filled with water. When using this device, first place the measuring plate with the tumor accommodation groove on the cutting device, regularize the edge of the measuring plate through the cutting device, and at the same time measure the length and width of the tumor accommodation groove through the cutting device. Then clamp the edge-regularized measuring plate on the clamping mechanism, and then inject the water in the syringe into the tumor accommodation groove. Calculate the tumor volume through the weight difference of the water in the syringe before and after.

[0025] In this embodiment, the measuring plate can cover and solidify the elastomeric impression material for different tumors on the body surface that are relatively close in distance together, and then separate them by cutting through the cutting device.

[0026] In this embodiment, in order to achieve preliminary size measurement of the tumor clearance groove, the cutting device includes a square ruler 15, a scale 16 is provided on the inner right-angle edge of the square ruler, a fixing plate 17 is provided on the edge of the outer bracket of the square ruler, the fixing plate is screwed on the workbench, the measuring plate is placed in the square ruler, the edge is first rested, and then the edge of the measuring plate is placed against the square ruler, and the preliminary size measurement of the tumor clearance groove can be achieved through the scale. Furthermore, the cutting device also includes a telescopic right-angle block 18, the telescopic right-angle block includes a horizontal transverse block 19 and a horizontal longitudinal block 20, the horizontal transverse block includes a limiting portion and a sliding portion, the limiting portion is provided with a sliding groove hole 23 on the middle part of one side of the sliding portion, and a sliding rod 24 is provided on the side of the sliding portion facing the limiting portion corresponding to the sliding groove hole, and the sliding portion is away from the limiting portion. One side of the positioning part is fixed on the outer side of one end of the horizontal longitudinal block, and a bolt 25 for fixing the sliding rod is screwed on the limiting part. The telescopic right-angle block is used to assist in dimension measurement. The telescopic right-angle block can be quickly aligned with the scale line and the edge of the tumor yielding groove, which is convenient for dimension measurement. At the same time, when cutting is required, the horizontal longitudinal block can also limit the cutting position of the cutter. Specifically: a vertical cutting groove 26 is opened in the middle part of the horizontal longitudinal block along the length direction, and the cutting groove runs through one end of the horizontal longitudinal block connected to the sliding part, so that the horizontal longitudinal block is formed into a U shape. When in use, the sliding part is driven to move by the horizontal longitudinal block, and then the sliding rod is driven to extend or retract into the sliding groove hole. When the horizontal longitudinal block moves to the required position, the sliding rod is tightened by the bolt to fix the length of the telescopic right-angle block, thereby determining the position of the cutting groove.

[0027] The cutter assembly is slidably connected to the horizontal longitudinal block in this embodiment, and the cutter assembly includes a sliding bracket 27, and a vertical cutter 28 is slidably connected to the sliding bracket corresponding to the cutting groove for lifting and lowering; more specifically: the sliding bracket includes a sliding seat 29 symmetrically arranged on the left and right, and the front and rear sides of the upper parts of the two sliding seats are connected by a connecting plate 41. The sliding seat is L-shaped, with the horizontal part at the bottom and the vertical part at the top. The ends of the horizontal parts of the two sliding seats are respectively slidably connected to the two sides of the length direction of the horizontal longitudinal block, and the cutter is slidably connected between the vertical parts of the two sliding seats, that is, the gap between the two sliding seats is slidably connected to the outside of the horizontal longitudinal block. Through this sliding connection, on the one hand, it can assist in the movement of the cutter. On the other hand, since the gap between the two sliding seats and the position of the horizontal longitudinal block have been determined, the cutter is aligned with the cutting groove in real time during cutting, and no cost is incurred. At the same time, in order to cut as much as possible with the cutter, the two ends of the cutter can extend out of the sliding bracket.

[0028] In this embodiment, in order to achieve the sliding and resetting of the cutting knife, the cutting knife is connected to the vertical portion of the sliding seat through a sliding connection structure. The sliding connection structure includes sliding mounting plates 30 symmetrically fixed to the side portions of the cutting knife on the left and right. A plurality of horizontal sliding plates 31 are arranged at intervals along the length direction on the sliding mounting plates. Vertical sliding grooves 32 are provided on the vertical portion of the sliding seat corresponding to the ends of the horizontal sliding plates. The ends of the horizontal sliding plates are slidably connected in the sliding grooves. A spring mechanism for driving the horizontal sliding plates to reset is arranged in the sliding grooves. During use, the cutting knife presses down to cut the silica gel plate and then resets through the spring mechanism.

[0029] In this embodiment, the specific structure of the spring mechanism is as follows: The spring mechanism includes an upper limit post 33 and a lower limit post 34.

A reset spring 37 is installed between the lower end of the sliding groove and the end of the horizontal sliding plate. The two ends of the reset spring are respectively sleeved outside the upper limit post and the lower limit post. The limit sliding post is lifted by the reset spring, which facilitates the resetting of the cutting knife after it is pressed down.

[0030] In this embodiment, for reasonable design, a knife handle is provided at the upper end of the cutting knife. The knife handle includes a pressing plate 38 arranged horizontally. A vertical connecting plate 39 is installed under the pressing plate. The vertical connecting plate is fixed to the cutting knife. The two sliding seats and the front and rear connecting plates enclose an extending area. The knife handle extends upward from the extending area. The cutting knife is pressed down by pressing the knife handle.

[0031] In this embodiment, in order to measure the volume of the tumor displacement groove on the measurement plate, the clamping mechanism includes a clamping bottom plate 7. T-shaped grooves 8 are symmetrically formed on the left and right of the clamping bottom plate. Clamping bases 9 are slidably connected to the front and rear of the T-shaped grooves. T-shaped bolts 10 are provided on the clamping bases corresponding to the T-shaped grooves. The cooperation of the T-shaped grooves and the T-shaped bolts realizes the sliding and fixing of the clamping bases on the clamping bottom plate. A vertical clamping support rod 11 with scales is installed on the clamping base. A clamping lifting block 12 is slidably connected to the clamping support rod.

A bolt for pressing against the horizontal clamping rod is also provided on the side of the clamping lifting block to realize the fixing and loosening of the horizontal clamping rod. A fixing clip 14 is installed at the end of the horizontal clamping rod. The fixing clip can be an existing elastic clip. Both the horizontal clamping rod and the clamping support rod are square rods, which are convenient for fixing the height of the fixing clip and preventing the fixing clip from rotating. At the same time, two clamping bases are provided on both of the left and right T-shaped grooves, that is, four clamping bases and four fixing clips are provided. The four corners of the measurement plate are fixed by the four fixing clips, so that the four corners of the measurement plate are at the same height, which is convenient for adding water to the tumor displacement groove.
